-#
-# For "make pdfdocs", reports of build errors of translations.pdf started
-# arriving early 2024 [1, 2]. It turned out that Fedora and openSUSE
-# tumbleweed have started deploying variable-font [3] format of "Noto CJK"
-# fonts [4, 5]. For PDF, a LaTeX package named xeCJK is used for CJK
-# (Chinese, Japanese, Korean) pages. xeCJK requires XeLaTeX/XeTeX, which
-# does not (and likely never will) understand variable fonts for historical
-# reasons.
-#
-# The build error happens even when both of variable- and non-variable-format
-# fonts are found on the build system. To make matters worse, Fedora enlists
-# variable "Noto CJK" fonts in the requirements of langpacks-ja, -ko, -zh_CN,
-# -zh_TW, etc. Hence developers who have interest in CJK pages are more
-# likely to encounter the build errors.
-#
-# This script is invoked from the error path of "make pdfdocs" and emits
-# suggestions if variable-font files of "Noto CJK" fonts are in the list of
-# fonts accessible from XeTeX.

-#===========================================================================
-# Workarounds for building translations.pdf
-#===========================================================================
-#
-# * Denylist "variable font" Noto CJK fonts.
-# - Create $HOME/deny-vf/fontconfig/fonts.conf from template below, with
-# tweaks if necessary. Remove leading "# ".
-# - Path of fontconfig/fonts.conf can be overridden by setting an env
-# variable FONTS_CONF_DENY_VF.
-#
-# * Template:
-# -----------------------------------------------------------------
-# <?xml version="1.0"?>
-# <!DOCTYPE fontconfig SYSTEM "urn:fontconfig:fonts.dtd">

-#
-# The denylisting is activated for "make pdfdocs".
-#
-# * For skipping CJK pages in PDF
-# - Uninstall texlive-xecjk.
-# Denylisting is not needed in this case.
-#
-# * For printing CJK pages in PDF
-# - Need non-variable "Noto CJK" fonts.
-# * Fedora
-# - google-noto-sans-cjk-fonts
-# - google-noto-serif-cjk-fonts
-# * openSUSE tumbleweed
-# - Non-variable "Noto CJK" fonts are not available as distro packages
-# as of April, 2024. Fetch a set of font files from upstream Noto
-# CJK Font released at:
-# https://github.com/notofonts/noto-cjk/tree/main/Sans#super-otc
-# and at:
-# https://github.com/notofonts/noto-cjk/tree/main/Serif#super-otc
-# , then uncompress and deploy them.
-# - Remember to update fontconfig cache by running fc-cache.
-#
-# !!! Caution !!!
-# Uninstalling "variable font" packages can be dangerous.
-# They might be depended upon by other packages important for your work.
-# Denylisting should be less invasive, as it is effective only while
-# XeLaTeX runs in "make pdfdocs".
-

+A "normal" jobserver task, like the one initiated by a make subrocess would do:

+ - ask for one slot by calling:
+ claim = os.read(reader, 1)
+ - when the job finshes, call:

+Here, the goal is different: This script aims to get the remaining number

+parallel. To to that, it has a loop that ends only after there are no
+slots left. It then increments the number by one, in order to allow a
+call equivalent to make -j$((claim+1)), e.g. having a parent make creating
+$claim child to do the actual work.
+
+The end goal here is to keep the total number of build tasks under the
