I'm seeing the exact same thing. I'm running -current from yesterday 
and this box is lightly loaded. I can't track it down to a specific 
process, but all of a sudden normal compiles are running me out of 
vm. This box has 500Mb ram and a gig of swap and has never run out of 
memory before. None of my applications have changed. I'm also 
starting to see it on a client's box I recently updated to 7.0, That 
box has 1Gb ram and 2Gb swap and is just a desktop and mailserver.
I don't think this is application related.
