Unfortunately building pypy myself didn't really achieve anything for my own
code.  PyPy behaved really bizarrely for example claiming functions don't
exist in my test code (standard unittest).  I get different behaviour if I
run under gdb or not.  Additionally objects aren't particularly useful.
With CPython there are some nice macros supplied with a .gdbinit, especially
pyo so you can tell what is going on.  Pypy is behaving like a randomized
black box!

If anyone wants to try for themselves then the code is at
