[Bug] Importing gevent causes sandbox errors

[cretz]

Describe the bug

from gevent.os import fork

Seems that causes the sandbox to fail

[cretz]

This is happening due to https://github.com/gevent/gevent/blob/1e412d35526183b26c1abf2eb658cbef661f5f70/src/gevent/os.py#L539 where https://github.com/gevent/gevent/blob/1e412d35526183b26c1abf2eb658cbef661f5f70/src/gevent/_util.py#L90 is accessing __dict__.items() of the module

[cretz]

This is caused by dict.items(our_restricted_proxy_wrapper_of_a_dict) which raises:

TypeError: descriptor 'items' for 'dict' objects doesn't apply to a '_RestrictedProxy' object

This is checked in C code and we can't fix it. Will suggest work arounds.
