> Trying... but it seems to have major problems with python2.2.
Ah, fiddlesticks -- does someone here still give a rip about Python 2.2? I
don't. 2.2 is dead -- it's no longer maintained, 2.3.3 is out and
universally regarded as stabler & faster than 2.2.3, and development has
moved on to 2.4. I'd like to drop all our 2.2 compatibility cruft; it's a
growing mass of dead weight.

Right, it wouldn't. The easiest pithy explanation is that file objects in
2.2 *have* iterators, but file objects in 2.3 *are* iterators. To use the
same style of code under both requires getting an explicit iterator,
it = iter(fh)
and then doing
for line in it:
everywhere instead of
for line in fh:
As is, the
for line in fh:
lines under 2.2 are really jumping across internal file buffers. That was
crazy behavior, and that's why it got repaired for 2.3 (but the fix couldn't
be backported to 2.2 lest some crazy code relied on the broken behavior).

Not your fault: it's not possible to find out time of day under 2.2 either
