RR, S: 7162400 Intermittent java.io.IOException: Bad file number during HotSpotVirtualMachine.executeCommand

[Dmitry Samersoff]

Alan,

Client detaches from target VM for some reason, so we get EBADF from
native layer.

It happens rare - once for 1000 iterations or so, depends to hardware,
so I'm not sure we should fix it.

Serializing enqueue() call we reduce probability of it ever more.
