Yes, but if the several threads are all trying to access a resource that 
is protected by a mutex (i.e. like a list of users or something, or the 
iax lock, etc), then only one thread will be able to execute at a time..

For this problem, it would be most instructive to build asterisk with 
-pg, and then see where it's spending all it's time..
