Subject Re: general/8826: Threaded mpm creates large number of processes.

Linux is, nothing to do with Apache...

In this case the PID's are all different. That looks like different processes
to me, rather than multiple threads inside a process. This is the output of
"ps wwalx" with
	StartServers 	     1
	MaxClients         150
	MinSpareThreads     25
	MaxSpareThreads     75 
	ThreadsPerChild     25
	MaxRequestsPerChild  0
