efreet cache - handle corner case where efreetd keeps disconnecting 

so an odd one. there is a socket, but nothing is actually listening on
it, but clients keep spinning launching efreetd's because the launch,
connect, then get a disconnect and try again immediately keeping
things spinning heavily, so add a delay of 0.5 sec before launchnig
another efreetd if the launch + connect fails and gets a disconnect
within 0.5 sec ... so give up for 0.5 sec before trying again to avoid
a runaway system.
