profiling only part of a program

[Glen McCluskey]

Is it possible to use the `-pg' flag to profile only
part of a program?  For example, if you don't use the
flag except for loading, you will get a profile of
the library routines and system calls.

The tests I have done seem to show that you can get
reliable call counts, but not reliable times, this way.
Can someone verify this?
