Summary: cleanup() not called when openser is killed

Initial Comment:
Hi,

When the main process receive a SIGKILL (or SIGINT) signal it call kill_all_children(SIGTERM) but it never returns from this function. So, it never calls cleanup(1) and the destroy_function() of each module is never call. 

But, when I kill a child the main process receives a SIGCHLD signal and, in this case, every thing works normally: The destroy_function of each module is call. This situation gives a chance to (my) module to close files, network sessions and kill its own child.

Tested on SunOS 5.8 and 5.10 with openser 1.2.0

Hi,

Based on the tests I run (following your report), I was not able to
reproduce this behaviour at all. 

The kill_all_children() cannot block as it only sends signal by using
kill(), which is a not blocking operation.

I suspect the problem is somewhere else located (like this is side efect
of another bug). If you can still reproduce this, try to get more on this
(gdb inspection, CPU consumtion, etc) and open a new report.

regards,
Bogdan
