{{FGCquote | |||
|Nasal's garbage collector requires that no other Nasal threads are <br/> | |||
running, and achieves this by keeping a count of active Nasal threads <br/> | |||
(nThreads, simgear/nasal/code.h), and having the thread that needs GC <br/> | |||
ask all other threads to stop and wait until nThreads-1 say they have <br/> | |||
(bottleneck(), simgear/nasal/gc.c). This will hang if there are any <br/> | |||
threads that Nasal thinks are active but actually aren't, as they will <br/> | |||
never reply to the stop request. | |||
