[pypy-dev] Circular reference when importing struct from a pypy sandbox.

[Jonathan Slenders]

Hi everyone,

Not sure whether this is sandbox related, but I get a circular reference
when I want to import struct.py
The problem seems to be in the MixedModule import which get to import
himself somehow...
Anyone here who likes to take a look at the trackback below?

Actually, I'm not entirely sure whether I have the correct sys.path inside
the sandbox.
But anyway, I already had a great experience with the sandboxing mode.
(Right now, I'm rewriting sandlib to something usable in Twisted Matrix,
amazing technologies they are.)

Cheers,
Jonathan
