A few trivial and one more subtle bug prevented any seriously-sized test to
complete. I fixed it.

The pystone benchmark is not at all typical Python code :-)  psyco still
performs a x2 speed-up but this is not representative of possible results
(it suffers from missing knowledge about integer multiplications and
divisions as well as (more importantly) methods of user classes).
