I have been monitoring this thread closely, because we use quite a few Macs
here that I would like to replace their X terminal software with VNC.  Some
are using system 7.6.1, some are using 8.1.  None are exhibiting this large
memory leak.

sample machines are:
PowerComputing PowerCenter 150 w/16mb ram, using VM to get 48mb.  Using
7.6.1 with OT 1.1.2 over ethernet (10bt).  System heap at start: 11,921k
System heap after several HOURS of using the VNC client, including the
switching between apps as defined above: 11,949k

PowerMac G3/266 with 160mb ram, no VM, running system 8.1, and OT 1.3 over
10bt ether
system heap stays at 16.7mb.

I would start looking at other system extensions you have enabled....
