I've just added a new benchmark test to lp:~zeitgeist/zeitgeist/no-
table-cache, test/cache-test.py, which inserts 1000 events with a
different interpretation each (could as well -and more likely in the
real world- be 1000 different mimetypes or actors, but the code is
basically the same for all of them so I just tried with interpretations)
and then retrieves them one by one filtering by their interpretations.

This benchmark shows us that the cache is indeed justified, so now we
know it's worth to fix it :).

Times (in seconds) with current trunk and having removed the cache:
 - Insertion: 0.22 0.34
 - Recovery: 0.19 1.90

Here's the same with 100 events and interpretations instead of 1000:
 - Insertion: 0.02 0.032
 - Recovery: 0.02 0.035

And with 10 events/interpretations:
 - Insertion: 0.0025 0.0035
 - Recovery: 0.0021 0.0022
