Log:
pypy-c _finally_ built, so add some (not too good) performance numbers.

looking at the c source reveals that the inlining is not as thorough as we

cleanups are not inlined (presumably 'except' cleanups have the same problem).

maybe it should be an except block and a cleanup block, or something.

 This week Michael with the help of Carl, Samuele and Armin managed for
 the first time to compile the pypy interpreter together with our own

+collector for performance at all, this isn't too bad.
 
 This required quite a bit of work and first we refactored the way the
