Details

It would be nice if the profiler could voluntarily reduce its memory usage when requested by a "memory-pressure" notification.

Special care may be needed around IPCs, to avoid confusion when buffer sizes suddenly change, and some in-flight DestroyReleasedChunksAtOrBefore messages become obsolete.

This could be combined with bug 959337: Both bugs need to listen to "memory-pressure", to record the event while profiling, and reduce the profiler's own memory usage if possible.
