Subject: 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.
