This fixes issue7900 by adding code that deals
with the fact that getgroups(2) might return
more that MAX_GROUPS on OSX.
See the issue (and python-dev archives) for the
gory details. Summarized: OSX behaves rather oddly
and Apple says this is intentional.

+- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
+ compared to other unix systems. In particular, os.getgroups() does
+ not reflect any changes made using os.setgroups() but basicly always
+ returns the same information as the id command.
+
+ os.getgroups() can now return more than 16 groups on MacOSX.
