10-CURRENT and swap usage

	I build out of my UFS-only VM in VMware Fusion from time to time, and it looks like there's a large chunk of processes that are swapped out when doing two parallel builds:

last pid: 27644;  load averages:  2.43,  0.94,  0.98                                                                                                                                up 1+15:06:06  19:20:48
79 processes:  4 running, 75 sleeping
CPU: 77.3% user,  0.0% nice, 22.7% system,  0.0% interrupt,  0.0% idle
Mem: 407M Active, 186M Inact, 208M Wired, 24M Cache, 110M Buf, 145M Free
Swap: 1024M Total, 267M Used, 757M Free, 26% Inuse

	I know that some minor changes have gone in in the past couple months to change when swapping and page ins/outs would occur, but I was wondering if this behavior was intended; I'm finding it a bit bizarre that there's ~150MB free, ~180MB inactive, and 267MB swapped out as previous experience has dictated that swap is basically untouched except in extreme circumstances.
Thanks!
