Stack size

[Cat Okita <cat () reptiles org>]

In the process of doing some trivial (and admittedly sloppy) programming
recently, it became apparent that OSX has a surprisingly low stack size
of 512K (measured via getrlimit, to show the current (soft) limit, and
the hard limit).

Checking other (albeit not the same hardware architecture) systems for
curiousity, it seems that it's much more common to have a stack size
of 8Mb.

Is there any particular reason why it would be advantageous to have
such a small stack size?

Are there any particular security concerns about changing the stack size?

cheers!
