Hi Edward

Many thanks for the information.  It's great to hear that worker MPM 
will be supported in the 2.2 version.  If the code can be backported to 
2.0, then that would be a huge bonus, too.

If at any stage you need help with beta code testing for 2.2?  I'd be 
more than happy to help out.  I have access to Centos/Redhat 4/5, Suse 
9/10 and FreeBSD 6.2 machines.

Many thanks.

Regards, Paul
