Running `python -c "import numpy", I get a recursion error. Running a lldebug0 build under gdb, here is the backtrace.

Searching for cpyext, I see there is a chain starting around frame 75 that maybe I can do something about. 
But why are there 40 recursive calls to `pypy_g_dispatch_bytecode__AccessDirect_None` ?
