Subject: IOC Threads blocking all signals

Question:
It seems (looking at start_routine() in libCom/osi/osd/posix/osdThread.c) that all threads that the IOC starts are blocking all signals.
Is that correct, or am I missing something?
If that's correct, why is it done?

We have a case where a separate process started from an EPICS IOC subordinate (driver) thread - via fork() and execv() calls - seems to be "immune" against all attempts to kill it (except -9 obviously).

Any ideas?

Thanks a lot,
~Ralph
