It reduces stack allocated for each thread in pthread_create().
The default max stack is 512MB, while the ARCH_STACK_MAX_SIZE is 32MB.

When the getlimit() returned RLIM_INFINITY,
the used stack for each thread is 32 MB,
but when it returned any real number, the real number have been used.
The patch adds upper bound (128MB) of pthread stack size.

During pthread_create() is the stack (pre-)allocated via mmap(),
i.e. 524288 have been even larger than 512000.

On kfreebsd-i386, the default max stack is 64MB, while the 
ARCH_STACK_MAX_SIZE is 8MB, the memory limit
512000 have been therefore sufficient.

Cheers
