Wow, I'd stick with the vanilla Spidermonkey for now...By far my favorite thing about CouchDB
is the fact that I can run it on a 256Mb server along-side my web app and it churns and burns
happily even when the load begins to kick up.  Couldn't be happier with it.  Thanks for the
"testing" Jan :)

2x speed for 10x mem consumption on my ad-hoc,
non-scientific testing. The keeping-memory-down
methods of Spidermonkey either are not in place yet
or I was doing it wrong. But i didn't spend a whole lot
of time one it, so take this with a grain of salt.

Yes, I had to try that immediately :)

PS: Sorry for the empty email earlier.
