Summary: chown broken on 64bit
Initial Comment:
python-2.5 on fedora fc7 x86_64:
os.stat returns uid > 32bit:
os.stat ('shit')
(33204, 4420723, 64768L, 1, 4294967294, 500, 0, 1183558507, 1183558507,
1183558517)
os.chown doesn't like that:
os.chown ('shit', 4294967294, 4294967294)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OverflowError: signed integer is greater than maximum

Indeed, in Modules/posixmodule.c::posix_chown(), the uid and gid variables
are defined as type 'int'. They should be of type 'uid_t' and 'gid_t' which
are mapped to 'unsigned int' on at least some Unix platforms (I haven't
checked extensively.)
The wrinkle here is that chown() needs to be able to handle the case of
uid/gid set to -1, which means to leave them as is. Therefore, os.chown(-1,
-1) is valid, but so is os.chown(4294967294, 4294967294).
