Multithreaded?

[Greg\(Bear\) Casad]

All installations of mysql I have run ps -fax will show about 5 mysql proccess 
running, even at idle.
I compiled on a Redhat 9 box, it did find pthreads.... however ps -fax show 1 mysqld 
process running.
Is there a spot to configure spare proccess? -- Or verify that it is indeed compiled 
muli-threaded??
