Oh yeah, good idea. Signals and their handling make most people cringe.

Also, selftests. I wonder if it would be a good idea to make it a
kernelnewbies project for people to do short programs, each exercising
an API from the Linux manpages.

Or maybe even get Michael (CCed) to donate some of the examples from his
book:

https://man7.org/tlpi/code/online/all_files_by_chapter.html

in this case, chapters 20-22, as selftests for the kernel. Or maybe even
all examples. :-)

Just an idea anyway.

Thx.
