threads within threads

Hi
I am attempting to create a boost thread within an existing boost 
thread, i.e. a function called by the operator() function of an 
existing, running thread is attempting to make more threads. The new 
threads function objects are of the same type, but different from the 
parent function object type.

This compiles and runs, but takes time equivalent to the threads 
running sequencially on a single thread. CPU usage indicates that 
both threads are running in parallel. Very strange...

I am building with gcc v3.2.3 on red-hat linux build 2.4.20.
Any ideas gratefully received!
