Why would use a fixed size queue? When I built the CORBA Events based logger
I made the Q a linked list!
I could see putting a cap on the size of the Q to avoid having it overwelm
the JVM heap if the l/O thread isn't keeping up... But I would think that I
would set this max pretty high and not expect to hit it. If I was regularly
maxing out here, I'd have some "volume" settings to regulate the number of
messages being logged.
