Cross-database relations in SQLAlchemy?

Set out to make an app use two different databases today; one for a high-write-volume set, the other for low-volume mostly-read set.  It's a TurboGears 2.0 application using SQLAlchemy.  I'd half-way hoped for "tell these tables they're in that db" and then have the ORM figure out all the magic of which session to use ...

Dreaming of deterministic profilers future...

Some things it occurs to me that I'd like to see in a new Python profiler:

Ugh, lost suspend-resume on the laptop...

Since updating to Ubuntu 11.04, my Thinkpad has, at long last, been able to resume.  Unfortunately, it has also suffered lots of X crashes/hangs from KDE software.  That's kinda frustrating, so I decided to try updating to KDE 4.7 on 11.04, to see if that was more stable.  Unfortunately, the machine is back to never ...
