On our 3B20 (although the problem is probably generic), it seems that 
when I exceed the maximum space allowed for the stack, my process gets 
sent a segmentation violation signal.  I would like to catch (and handle) 
it but I have no room left on the stack for the signal catching routine.
I can try to do a setjmp() at the beginning of the series of calls that 
cause the problem and then try to do a longjmp() in the catching routine, 
but I really need to hold my breath and hope that there is enough room 
for this (small) catching routine to execute. (long sentence, eh?)

Any other suggestions (besides "use a machine with demand
paging/virtual memory") ?
