something similar.
Isn't that what the leader-follower MPM does?
Ah.. I didn't see the leader-follower stuff (I'm probably too focussed 
on
worker MPM). Thanks for pointing it out !

Has there been any analysis done on the leader-follower MPM already ?
I did some comparisons between leader-follower and worker a long
time ago.  At that time, worker was slightly faster than leader-follower
on multiprocessor Solaris servers, but the code has changed since
then, and the performance characteristics of both are likely to vary
among operating systems.  If you have the time to test it, it wouldn't
hurt to compare leader/follower to worker in your current benchmark
environment.
