GPROF: GNU gprof 2.17.50.0.6-5.fc6
UNAME-A: Linux <myhost> 2.6.20-1.2962.fc6 #1 SMP Tue Jun 19 18:24:12 EDT 2007
i686 i686 i386 GNU/Linux
On single core CPU's and older kernels the cumulative seconds column converged
well towards the user time for the executed command. On multi core and SMP
machines this seems way off - not half (for dual core) - just something.
Reproduce: I have a simple C program to demonstrate this.
