This may be restating the painfully obvious, but note that
(run-until-halt) (or runUntilHalt()) never returns, until (halt) or
halt() is called. Generally, then, a given script can only call
(run-until-halt) at its end; likewise, any one Java thread is tied up
once it has called runUntilHalt(). The trick to using run-until-halt
and then subsequently asserting more facts is that you have to use
multiple threads. Jess's script language doesn't offer any immediate
way to run things in a new Thread, but it's easy enough to do from
Java.
