So I'll start making patches like:
if ( (LvdDevice *dev = gContext->GetLcdDevice()) )
which would not affect the current behavior at all, and then in the end send
the patch which really does not create and/or deletes the lcd object if it's
unable to connect to it's server.

I was thinking why calculate time x is over y, z times a second for such a
minute task as updating the lcd display, which could live well with a bit of
a delay on very high load.
