Jason Evans 91e92a2d3d Don't explicitly mmap() red zones at the bottom of thread stacks (except ... the initial thread). Instead, just leave an unmapped gap between thread stacks and make sure that the thread stacks won't grow into these gaps, simply by limiting the size of the stacks with the 'len' argument to mmap(). This (if I understand correctly) reduces VM overhead considerably. Reviewed by: deischen		1999-12-29 15:44:59 +00:00
