Now internal representation of Struct with small format string may
consume unexpectedly large memory and this representation may be
invisible cached. With patch you can get large internal representation
only for large format strings. It is expected.
And how about struct_sizeof.patch? Now sys.getsizeof() returns wrong
result for Struct:
28
>>> sys.getsizeof(struct.Struct('100B'))
28
The patch (it compatible with both Struct representations) fixes it:
52
>>> sys.getsizeof(struct.Struct('100B'))
1240
