Is anyone else having trouble with Xcode 3 using a lot of memory?

I've previously seen it using over 700MB of memory. This is after
closing all the
projects I had open, which I would assume should free any associated
memory. I
had a go at using MallocDebug to work out where the RAM is being
used, and it seems
to be related to syntax highlighting. Is this a known problem?
The VSIZE is largely irrelevant for an application like Xcode. Given
the number of files it is messing about with, a good sized chunk of
the address space is going to be consumed by mapped files.
RSIZE is more interesting, but still not great. The vmmap and heap
commands are much more interesting.
As well, check top and see if your machine is paging.
