There is something a bit like this in the code.  The middle layer of the daemon
has to notice when a device has not sent data in too long and should be dropped
put of the pool, lest a deads or disconnected GPS hold open a pool slot and
a file descriptor indefinitely.

I'm guessing that what you want is something like a JSON notification when
a device is dropped?
