We did ourselves a big disservice by not pointing out clearly in the
todo list that most of the listed problems are VERY RARE and are
unlikely to affect most/all users.  In future we're going to have to
be clearer about that, because you're not the only user who was scared
for no reason.

We really had to push FreeBSD hard to find those problems; 6.1 stands
up to enormous test loads that all previous tested releases could not
handle.  I wouldn't be surprised if 4.x cannot handle the same
workloads, simply because no-one may have ever attempted such loads on
a 4.x system.


P.S. If you're willing to put some effort into analyzing and profiling
it, I'd be willing to work with you on your performance problem.
