Psyco3: nice typo! :-)

Well, I haven't so far found a new idea there that I'd want
to borrow and did not know from PyPy, before.
Wasn't the project plan saying the opposite, borrowing
some ideas from psyco? :-)

Yes, the profiler hooks are not useful with psyco. You need
to write extra functions for timing, as we do in the benchmark
directory.

The profile() function is used for profile driven compilation,
as opposed to psyco.full(). This will go away, pretty soon.
Psyco will only be switched on or off.

Maybe I will add an option for profiling the compiled code.
Interesting idea!
