	I'm seeing a failure (when running the dante test script).
The failure is that the Principal for the DanteProtocol thread is set
to "RemoteUsers" instead of "DanteUser".  Sometimes it succeeds, I
think, but most of the time it fails for me.  My test system is
bro.isi.edu: FreeBSD bro.isi.edu 3.2-RELEASE, jdk-1.1.8.

	The following trace output is for a modified "dante.{start,conf}"
and "nodesetup.sh".  I've also added additional trace statements and
stack dumps in the code.

	My working assumption is that there's a timing error, possibly in
"AppBooster.java";  then again, it could be something else, I don't
understand the code.
