This 1200 (May 4 sup) has been up for much, much longer than even just the
April 27 sup. I just finished a *concurrent* ./build.sh and a make update
of libtool that cascaded down the pkg tree, all while serving e-mail, being
a corporate webserver, and maintaining some 60 other processes. Two
1. 1200's are fast ;)
2. and very, very stable on MP now.
Muchas gracias to all.
