> The bug here is in java (not MMapDir), but i think we shoudl do something.
> Users get confused when they configure their JVM to trigger something on OOM,
> and then see "OutOfMemoryError: Map Failed": but their trigger doesnt fire.
> Thats because in the jdk, when it maps files it catches OutOfMemoryError,
> asks for a garbage collection, sleeps for 100 milliseconds, then tries to map
> again. if it fails a second time it wraps the OOM in a generic IOException.
> I think we should add a try/catch to our filechannel.map
