   For the stack allocation problem, one user solution I've though of may be
the use of a "watchdog" thread.  Each stack that you allocate for a thread 
would have a RAM semaphore associated with it which starts off being "set".
When a threat possessing such a stack wishes to terminate, it "clears" the
semaphore and exits.  The one problem is being sure that the thread is able
to exit before the stack gets reused.  But, anyway, the watchdog would hang
out waiting for stack semaphores to "clear", and would free the storage 
after a "reasonable delay" (long enough to be sure the thread was able to 
exit after the semaphore was cleared).  Anyway, while its pretty kludgy, 
it may be a possible route to consider.
