Thanks for the tips.  Very helpful.

I suspected as much, but got confused when I used the acceptCount
property and tomcat didn't complain.  acceptCount is only listed under
the "standard implementation" as well, so I expected a warning.

I was setting it as a property in the connector config.  Maybe that
was silly of me, but I thought maybe all the properties were localized
in the connector.  I just tried it as a command-line option and it
seemed to work.

Interesting side note, with
"-Dorg.apache.tomcat.util.net.NioSelectorShared=false" set and
selectorPool.maxSelectors="500".  My server code starts generating
comet END events after about 30 threads start and only about 10
seconds into the test.
