The following change (hidden in commit 426ea9b37283) breaks parallel on
Cygwin:
--8<---------------cut here---------------start------------->8---
@@ -5485,7 +5485,8 @@ sub compute_number_of_processes {
# The child takes one process slot
# It will be killed later
$SIG{'TERM'} = $Global::original_sig{'TERM'};
- sleep 10101010;
+ # 'exec sleep' takes less RAM than sleeping in perl
+ exec 'sleep', 10101;
exit(0);
} else {
# Failed to spawn
--8<---------------cut here---------------end--------------->8---
The symptom is that the process doing the exec plus the just execed
sleep (still shown as a child of perl) hang indefinitely until the
process gets HUPed or KILLed. I have not yet been able to figure out
exactly why this happens, a simple script doing the exec into sleep
works as expected, it might have to do with custom signal handlers.
Regards,
Achim.
