for debugging code to be enabled or not.

f2312262c7 Try moving the kill thread code into the thread_main() function so it can 
check if there are too many thread after it's finished with it's request.
Needs to be cleaned up further (if this is the right idea) because of the
locking around the servers_waiting variable.
 2001-09-06 21:16:35 +00:00
