Paul Adenot	679fac5442	Bug 848954 - Part 7 - Get rid of the stack allocated message queue. r=roc ... In the next patches, when the AudioDriver will be implemented, the audio backend thread (that we don't control), will return from the stack frame where the nsTArray that allows the MSG thread to exchange message queues in a efficient manner with the main thread. We put it in the MediaStreamGraph to avoid adding an allocation/deallocation per iteration on the MSG thread. In addition, the graph will be able to run on different threads during its lifetime, so we can't guarantee a stable stack frame to allocate things on anymore. The array are renamed with meaningful names, explaining the double-buffering pattern: the back queue is filled by the main thread, and is swapped with the front queue that is processed by the MSG thread. Arrays accesses are synchronized using the driver's monitor.	2014-08-25 15:26:21 +02:00
