Hi Peter:

That analysis is absolutely correct, and the current hang I am getting
for that post-install script
(/etc/postinstall/000-cygwin-post-install.sh) is a puzzler since that
occurs with or without the fork-fixed cygwin1.dll and the hang is new
behaviour compared to the result I got a month ago (obviously without
the fork-fixed cygwin1.dll) where I got an abort with an explicit
error message in agreement with the 24018 bug report. So I hope others
here with some cygwin experience will investigate further since I
might be doing something inadvertently different than before when I
replicated the behaviour reported in the 24018 bug report exactly.
