Summary: pwent objects from the pwd module ar e not pickle-able

Initial Comment:
cPickle.PicklingError: Can't pick
le <type 'pwd.struct_passwd>: attribute lookup
pwd.struct_passwd failed

There seems to be some name discrepancy in the pwd
module, and the pickling of a struct_passwd fails.

Works for me.  Reopen if you still have problems.

>>> import pickle, cPickle, pwd
>>> n = pwd.getpwnam('nobody')
>>> n
('nobody', 'x', 65534, 65534, 'nobody', '/', '/bin/false')
>>> type(n)
<type 'pwd.struct_passwd'>
>>> pickle.dumps(n)
"cpwd\nstruct_passwd\np0\n((S'nobody'\np1\nS'x'\np2\nI65534\nI65534\nS'nobody'\np3\nS'/'\np4\nS'/bin/false'\np5\ntp6\n(dp7\ntp8\nRp9\n."
>>> cPickle.dumps(n)
"cpwd\nstruct_passwd\np1\n((S'nobody'\np2\nS'x'\nI65534\nI65534\nS'nobody'\np3\nS'/'\nS'/bin/false'\np4\nt(dtRp5\n."
