	Sounds reasonable for -3-6 to me (but doesn't require approval there as
a bug fix:-).

	I would add a magic env-var to turn that on/off - so people can (at a
pinch) disable it if need be (and we can isolate it's effect better).

	We could add an easy hack or something. If we could abstract the
hoovering in some nice way in the code, so this is possible later, I'd
be happier - but - you're the boss in base :-)

	So - I'd just go for it, and wait for user feedback during 3.6 beta.

	Thanks !
