Yes, during dcrt startup, after signals are inited, a version check if
the daemon is performed. If no response is recieved, all daemon calls
are skipped and errors returned to the calling function. I'm thinking
about tweaking that, to perform that check at the first daemon call, as
this would avoid all delay associated with finding a dead daemon until a
daemon function was called. However this introduces more syncronisation.
It's a tradeoff really.
