Query cache plugin for rails 1.2

I love the query cache from rails edge, but I didn't want to put our
production app on edge just yet. (went down that route in the 1.1.x
days, and the edge cut me a few times). So I think I have it ported
into a plugin we can use on 1.2.x


Basically it's just a copy and paste job of the latest query_cache.rb,
the part that loads it from caching.rb, and its unit tests. Any
thoughts on this? Seems like it works perfectly, the query cache unit
tests run fine, and my app's running fine (i.e. tests are green). If
anyone sees any issues with this please let me know. Hope everyone
has a great weekend!

Cool, I'm sure other's still on 1.2.x will thank you.
