Hello,

I have found the cause of the crash that was occurring only on some 
deployments.  The cause is that sem_wait is interrupted by signal, and 
the wait operation is not retried (as is customary in posix).

Patch attached to fix

A big thank you to Vladislav Bogdanov for running the test case and 
verifying it fixes the problem.


Regards
