From this commit and a few hours into the future ScriptEngine will be unstable: 

* Speeding up ScriptEngine shutdown
* Sharing threads so that minimum total thread count for any amount of regions will be 2. (1 maintenance, 1 script execution)
You can choose more script exec threads if you want of course.
In this commit: Sharing maintenance thread between all regions.
