MySQL and libpthread

[Ganbold]

Hi,

I patched mysql with Daniel Eischen's patch that makes it use scope process 
threads.
Also I'm using SCHED_4BSD scheduler and now mysql behaves much better.
Mysql with libpthread runs without any crash since April 16th.
I have cvs sources from April 16th and mysql-4.0.18 from ports.
