Mmm. It is theoritically impossible that SIGNAL_raise_callbacks calls 
the post_event() function, as only one signal handler is registered by 
the interpreter at the moment, to handle child process termination. And 
this is not the post_event routine.

Can you try the last revision? I fixed some race conditions in the 
signal management routines. Maybe it could be the cause of these strange 
errors...
