Re: [rules-dev] stateless session getQueryResults
ok I've done some work on this now. The WorkingMemory is transient, so
querries will work, until you serialise - also added the ability to use
parameterised querries. I've also updated it so you can do
StatelessSessionResult.getGlobal(String identifier). The twist is
globals must be exported as part of the results - to achieve some level
of statelessness. Take a look at the jira and give me feedback, asap, as
this will be in 4.0.2 next week.

Actually there may be a compromise. getQueryResults() can be left, but
only works if you don't serialise, once we seriaise that method
becomes Disabled as the ruleBase and WorkingMemory are lost. I think
that will work and allow me to achieve the best of both worlds,
without breaking the API.
