Profiling a multi-process program

I'd like to profile a program that forks and spawns several child processes. I want to see how much time is spent in some of the functions. What profiler can handle this job?

I think you can do it with SystemTap - DTrace ideas implementation on Linux

It seems SystemTap is focused on profiling kernel functions and sysmtem calls, and isn't suitable for profiling user-space programs. DTrace seems nice, but isn't available on Linux AFAICS.

Oprofile works well for this.

It seems like the right tool. I'm having some trouble using it without crashing the system, but that's a topic for a different question...
