[rules-users] Multithreading Rulebase Parsing Threadsafe

[Edson Tirelli]

   Barry,

   We fixed all threading issues we were aware of in 4.0.5-4.0.7. So, it is
safe to use it now. Just make sure the only thing you eventually share among
threads is the rulebase. Do not share session or packages among threads.
