Summary: inconsistent behavior of map and imap

Initial Comment:
If you pass sequences to map and imap and
the sizes of sequences are not equal,
map and imap don't behave the same way.

The code below is a simple example.
The size of seq1 and seq2 is not equal.

>>> seq1 = [0, 1, 2]
>>> seq2 = ['a', 'b']
>>> import itertools
>>> for x,y in map(None, seq1, seq2):print x,y
...
0 a
1 b
2 None
>>> for x,y in itertools.imap(None, seq1, 
seq2):print x,y
...
0 a
1 b
