I'd noticed what seemed to be a leak when sending large status
messages; somewhere 8700 and 8900 or so bytes was the threshold for a
lack of release, but it wasn't easily reproducible. (The threshold
seemed to be constant within a bbwin service session, but varied
between stops/starts of the bbwin service.) If you look at
http://xymonton.org/monitors:lsmon you'll see my code to work around
this issue: invoking bbwincmd with uploadmessage instead of merely
putting the file in tmpPath when the file is bigger than LEAKYMAX.
