That's not exactly what I meant, at the behavior of a transaction

Hi -
My app uses memcache-backed sessions, and we just had a hiccup when

user suddenly got another user's session.
Anyone else notice a glitch at about 14:00 EST 10th March? Or should I

Not so hurry.
As for pytz footprint, it's ~600kB in size and can be lightning fast
if combined with caching in memcache (caching of tzinfo? why not...).
Combine this with Babel and you'll get everything you'd want to do
l10n.
