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
GNU bash, version 3.2.48(1)-release (x86_64-apple-darwin10.0)

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