I have a python program (snippet below) which does not want to seem to die
when I issue a sys.exit() inside the SIGTERM handler. The output below is
generated as the result of sending several SIGTERM signals to the process,
as a result of seeing that it had not died.
I don't think this is relevant, but the application has fork()ed a child
process (cdparanoia). The only thing I can think of is that somehow, there
is an exception occuring inside sys.exit(), otherwise why am I not seeing
the "Did not sys.exit()!?" output? Could it be that exit() is returning but
that the output fd's are already closed?
Verrry strange...and therefore I'm sure I'm making a brain dead mistake.
Thanks in advance,
A.
