Stopping single thread from multithreaded program?

Hi all,
I have one question about the functionality of the gdb. Is
it possible
to break in a single thread of a multithreaded program,
while the other
threads proceed with their execution? I want to single step
one thread,
while the other threads are still running. 
At this time I am only capable to stop the whole process
with all
threads. I am using linux with the pthread library on a PPC
target. 

Thanks in advance. 

Kind regards 
Holger Brunck

GDB does not yet support this, sorry.
