BTW, currently that feature is not in the new Application code I'm working
on. I could add it, but when we discussed it I didn't know of anybody
using that feature. It seems a bit too dangerous to allow a buggy remote
side to delay our shutdown by a long amount of time [depending on PB
timeouts]. I humbly suggest that an architecture which depends on being
able to send "one last message" is probably flawed.
