This function returns information about the current status of the garbage collector.
The first return value tells you how many kilobytes of memory is currently occupied
by Hollywood's VM whereas the second return value indicates the threshold in kilobytes
that should trigger the garbage collector. Whenever memory consumption exceeds the
specified threshold, Hollywood will automatically run the garbage collector.
You can also run the garbage collector manually or change the garbage collector
threshold by calling the CollectGarbage() function.
