Apparently SuSE 9.1's X distribution uses even bigger

buffers than the standard ones.  64kB appears to be enough
for a stack in that case, but let's just go nuts and make
the stacks enormous, so that it takes a few more doublings
of X's stack needs before we run into this problem again.

The VM system should take care of not actually using most
of the memory anyway.
