Dudes and dudettes. Statprof works for profiling guile-vm. If you ask
me, that's pretty sweet.
Here's a profile of loading (oop goops). It's long because, well,
syncase... also I had to increase the sampling frequency because
otherwise the results were really unstable.

Total time: 0.34 seconds (7/50 seconds in GC)
$1 = #<directory (oop goops) b7259830>
I'm not yet sure what to make of this. It seems like the compiler itself
can be sped up by a factor of two or so, which sounds nice. We'll see.
Anyway, glad to see that statprof works with the new vm.
