A related question:  Will producers sending messages with acknowledgment,
get a failed ack if a broker is out of disk space, or will messages get
buffered in memory successfully (resulting in a good ack, before failing to
be written).

It seems like it might be a good feature to have the broker auto-detect if
it's log dir is nearing full, so that there is some runway to gracefully
shutdown, while still writing any in memory buffered messages.  It could be
an optional threshold, like 98% full, or X Mb free, etc.
