Kind of looks like the threads are reported as using the
same resources as the parent, so each set of 11 related
java threads all report ~12Mb used, (summing to over
130Mb), when the correct figure is actually closer to 12Mb
total?
Interesting, someone ought to fix that.

Well, 'free' reports the following:
<5 tomcats up for ~20 hours, light load>
total used free
Mem: 127908 120840 7068
Swap: 232900 8360 224540
<./tomcat all stop>
Mem: 127908 73488 54420

<./tomcat all start>
Mem: 127908 104380 23528

<hit each site once>
Mem: 127908 111984 15924
Swap: 232900 7752 225148
So it looks like under normal circumstances I'm running
pretty light on real memory, but next to nothing has
been swapped out. I guess thats good?
Thanks for the assistance!
