Given that most mallocs align to 8-byte boundaries these days (also true of
pymalloc), it's impossible in reality to define a smaller object than
TimeStamp, provided it needs at least one byte of info beyond PyObject_HEAD.

Possibly, but hard to say, since speed of display is also an issue, and I
imagine also speed of range searches. At least 2.2 makes it easy to define
computed attributes, any of which could choose to cache their ultimate
value, but none of which would need to be stored in pickles.
