Martin Panter added the comment:
Did you consider blocking the signal before spawning the child? I haven’t used
signals much, so I could be wrong, but it seems sigwaitinfo() is meant to be
called with the signal blocked. Something like this:
pthread_sigmask(SIG_BLOCK, {signum})
try:
t0 = ...
... # Spawn child, call sigwaitinfo(), etc
finally:
pthread_sigmask(SIG_UNBLOCK, {signum})
self.assertGreaterEqual(dt, ...)
