Two python database questions

[Dan Stromberg]

Hi folks.

I'm working on some file indexing software, in python of course.

Over the course of working on it, I've come upon two python+database
related questions:

1) Is there a reason for the gdbm module in python 2.4.1 not to have a get
method?  This makes it a touch less dictionary-like.

2) Has anyone already written some sort of in-memory cache wrapper for
gdbm or anydbm or whatever?  As I'm writing this program, I'm finding that
there's an awful lot of disk I/O going on - it'd be great if there were
some way of keeping the n most recently used items in memory, and only
write them to disk when room needs to be made in the cache or when the
program exits?

Thanks!
