You are correct.  I've added a test case that creates the same situation
(just by doing "ulimit -s 1023" before running a test binary).  It hits the
assert as well.  (Production builds won't see this since they define NDEBUG.)

I made the initializer round the value taken from getrlimit up to page size.


Thanks,
Roland
