Ok, I'll look it up then in the archives. I was just missing context
in this area as I subscribed to the list < 3 weeks ago. I apologize
for being more curt than necessary when I'm busy :).

If it's a valid performance issue where NetBSD is beating the snot out
of FreeBSD in a particular area, then I'll look at where FreeBSD needs
to improve and propose it to the right people in the FreeBSD project.
It's in all of the BSDs best interests that they perform well.

Hmmm... it's a good question whether or not bash factors into that
equation *shrugs*, because some versions of OSX shipped with /bin/bash
as /bin/sh:

 /bin/sh --version
GNU bash, version 3.2.48(1)-release (x86_64-apple-darwin10.0)
Copyright (C) 2007 Free Software Foundation, Inc.
$ uname -a
Darwin XXX 10.6.0 Darwin Kernel Version 10.6.0: Wed Nov 10 18:13:17
PST 2010; root:xnu-1504.9.26~3/RELEASE_I386 i386

bash does have a lot more features than ash *shrugs*.
