The original patch from Ben Laurie some years ago was needed because
FreeBSD's default stack size was < 8k and this wasn't acceptable.
Both Linux and Solaris had reasonable defaults for stacksize, or grew the
stack as needed to a reasonable size.

Testing today and consulting documentation shows that the default stack
sizes on FreeBSD, Linux, and Solaris are all acceptable.  Linux can grow
to 2MB, 32bit Solaris defaults to 1MB, 64bit Solaris defaults to 2MB, and
FreeBSD defaults to 64k.

In my opinion FreeBSD needs to get with the program and provide a
reasonable default.  64k is enough for us, but might not be for others.
