Greetings, All!
Been doing some housekeeping in my Cygwin installation at work, and wanted to
change the owner of the files to something other than myself.
TrustedInstaller seemed like a good neutral target, but it took me a little
while to find out it is

That is not true. While FD_SETSIZE is defined as a fixed constant,
Linux kernel does not actually "know" (or care) about it.
So you can have an array of fd_sets, like this, in your cod

True but the complex code (that involves thread spawning, if that's what you're
referring to)

Whoever wrote this, was wrong (they might have never consulted the actual
kernel code, or were just
blindsided by FD_SETS

Correct, yet the comments in the header files (along with used values) should
be consistent :-)

That'd work for CYGWIN right away; but

The following packages have been uploaded to the Cygwin distribution.
This release updates to the latest upstream security patch release and
continues to use the Fedora patches from an earlier release (Fedora has
already switched to openssl 3.x).
* openssl-1.1.1q-1
* openssl-perl-1.1.1q-1
* libs
