[rules-users] FireUntilHalt

[Edson Tirelli]

   Which Drools version are you using?

   There are no "secrets", but you have to be aware that in this mode rules
will fire right away if they can. Also, if you are using 5.4.0.Final,
please read another e-mail I sent to the list today, as there was a
concurrency bug that was fixed in the 5.4.x branch that could cause NPE.
