I've certainly used gprof on single threaded programs and it worked fine 
(mostly under Solaris, but still quite a bit under Linux).

One issue has been that for some versions of distribution shipped GCCs 
had pretty broken/bad or incompatible Ada/debug/gprof support.

I know with CentOS 4 things are pretty broken.

Might be interesting to look into oprofile support (might require a 
kernel rebuild).
