Lua Add Emergency Garbage Collector
Derivative of work by RobertGabrielJakabosky
http://lua-users.org/wiki/EmergencyGarbageCollector
I've only implemented the not enough memory part and
expanded this idea to adding a mechanism to signal
the OOM condition of the plugin buffer which allows us to only
grab the playback buffer after garbage collection fails
(SO THE MUSIC KEEPS PLAYING AS LONG AS POSSIBLE)
