[Devel] all openser processes do not get killed

[Jeffrey Magder]

I remember running into this problem when I was developing the SNMPStats 
module.  In my case it
was because I had a printf() in a signal handler, which is not a thread 
safe function.  If the problem
is intermittent but tends to happen more when a certain module is 
present, perhaps either:

1) A function is called that is not thread safe from within a signal 
handler provided by that module or,
2) There exists some other signal handling race condition.

Unfortunately I don't have the time to look into it at the moment 
(wedding next week, house
planning, and of course working to pay the bills),  but I thought my 
experience with the SNMPStats
module may be helpful.

Cheers!
