On Windows 2000 (machinename isolinear), build65, both the SelectorTest
client and server produced errors that could not be duplicated when
run on another W2000 machine (belagio). The client and server were
launched from the same host.

This exception appeared again on W2000 server, machinename "infinityzero".
client error essentially the same, but server error shows the
EXCEPTION ACCESS VIOLATION (seen in ChannelLimit.java) with a bit more info:

This version of SelectorTest is essentially the same version
as in the workspace, the difference being in some arguments I
pass into the test. Please contact me for instructions on
how to execute this test from within my network harness.
