So do we need to recompile Guile with an option to enable profiling?
I don't think that's a very good idea... though it might be good to
optionally support it.

One way that I can think of is to count the number of VM instructions
executed in a procedure.  Since the execution time of most instructions
are not so much different, the number of instructions executed will well
represent the time spent in a procedure.  Maybe I will try this sometime.
