Use O_NONBLOCK when opening command pipe If qemu_proc.poll() returns None, then QEMU dies, then we open the command pipe, the open() call will hang waiting for the other side to pick up. By using O_NONBLOCK, we can error out if the other side of the pipe is not there (e.g. QEMU exited between poll() and open). Bug: 126917782 Change-Id: If239ba084a6478ebdc9b1913c2831790dafd1af1
