HOWTO: getting BISS-JDE to run.

[Stephen Crane]

UNIXProcess.exitValue() should throw IllegalThreadStateException if the
process is still running.  I would suggest adding the following line to
exitValue() before the return:

 if ( isalive ) throw new IllegalThreadStateException();

BTW, people seem to post bugs on the mailing list.  Is this where they
belong? Or is in the bug report mail address at transvirtual?  Or both?
