207	deprecate notifyOnDisconnect()	Zooko		"In my opinion, people should not try to write code that uses disconnection-notification. Tahoe-LAFS has one bit of code left that tries to use {{{notifyOnDisconnect}}}, and there is an open ticket to remove that last usage from Tahoe-LAFS: https://tahoe-lafs.org/trac/tahoe-lafs/ticket/1975

Please see also my complaint in https://tahoe-lafs.org/trac/tahoe-lafs/ticket/1768#comment:3, which says that foolscap's current {{{notifyOnDisconnect}}} sometimes fires 0 times (#140) and sometimes fires more than once when it was supposed to fire once.

Deprecating {{{notifyOnDisconnect}}} would solve #140 and #42, would make for less work for the foolscap maintainers in the long run, and would spur Tahoe-LAFS (which is probably the only user of {{{notifyOnDisconnect}}} currently) to hurry up and move off of it, and would deter other users from starting to rely on it."	enhancement	new	major	0.14.0	usability	0.6.4
