 Sorry for silence, i was completely busy with other interesting stuff...
 By this time i have calmed down and remade my thoughts...
 First, since i am interested, i will conduct the research about that code
between fork() and exec() and try to implement some test cases for it.
Perhaps this can have also something to do with #39825.
 Alternative idea. Looks like you don't like spawn() because it is poorly
documented and "isn't guaranteed to behave the same on all operating
systems". What if we implement posix_spawn() for Cygwin ? Would you like
that ?
 One more alternative idea. What if we clearly define spawn() specification
for Cygwin ? It can be based on the rationale that spawn() is there to offer
more performant version of fork() + exec(), and its behavior, ideally,
should strictly follow original semantics of this pair.

 Eli, Christopher ? Your responses to this ?

 P. S. Eli, what about my other work (abspath fix) ? I don't see it in GIT
log, and also i see no feedback, so... May be you just don't want to accept
anything, and i'm just annoying you ?

Kind regards,
