-The current Nasal garbage collector (GC) is known to influence the frame rate in FlightGear and occasionally cause stutter under certain circumstances. This is largely attributed to it being a fairly simple sequential mark/sweep collector, which needs to stop all operations, mark all reachable objects and free unreachable objects in an exclusive, single-threaded, fashion.

-In other words, the time spent in the GC is proportial to the number of active objects, even for objects which may not be running - just loaded.
