Hi all.

I am right now optimizing (well, who is not) a grid generator
code with gprof.
Now gprof tells me the total execution time is 44 seconds. 
The wall clock in fact indicates 87 seconds.
Recompiling without -pg and running the test case gives
82 seconds. 

Can this difference be explained somehow?

Writing this, I start to wonder if there is a missing factor
of 2 or so?
