After I setup a queue to do some processing I notice progress is using quite a bit of memory.
I'm running on a powerbook g4.

PID COMMAND %CPU TIME #TH #PRTS #MREGS RPRVT RSHRD RSIZE VSIZE
420 Progress 15.4% 2:22:06 25 207 1416 1.15G 9.97M 534M+ 1.41G

274 ffmpegX 0.0% 3:56.98 4 108 259 2.14M 8.19M 2.68M 243M
2682 mencoder 65.6% 2:00:18 3 31 132 24.9M+ 2.05M 20.7M+ 64.8M+


If there is any test I could do to help, let me know.
