pmcd on mac rsize ~1.8GB

[Nate Pearlstein <darknater@xxxxxxxxxxxxx>]

So I'm running:

Performance Co-Pilot configuration on coyoacan.home:

 platform: Darwin coyoacan.home 10.5.0 Darwin Kernel Version 10.5.0: Fri Nov 5 
23:20:39 PDT 2010; root:xnu-1504.9.17~1/RELEASE_I386 i386
 hardware: 2 cpus, 4 disks, 5887MB RAM
 timezone: EST+5
     pmcd: Version 3.4.0-1, 3 agents
     pmda: pmcd mmv darwin


on my mbp and imac.  As time goes on, the rsize grow to ~1.8GB.  This can't be 
right.  Anything I can do to track this down?  I'm not too familiar with mac 
profiling tools.

Thanks!
