This is a perfect example on how much help from FreeBSD shops and
testers can make a huge difference for our Project.
Nicholas and DesertNet were so eager to fix the bug that they gave me
access to their 24-ways for several nights (and built a very nice
debugging environment) as the bug was not really obvious.
gianni@ spent some time writing down a prof-of-concept and testing
several revisions of the patch (with several different compiling
options).
pho@ stress-tested several revisions of the patch finding not-really
trivial bugs.

I really want to acknowledge these guys for the 'underway' hard work
they perform and really want to hope to see other people following the
same footprints. Testing is often as important as developing patches.
