Thats my reaction too, but I cant think of a good reason why. Ignoring=20
practicalities of the current implementation, it sounds like something th=
at=20
*should* be possible.

MountedStorage only opens its storage on demand, and closes the storage w=
hen=20
no longer needed. I dont see this is a problem unless you need ZEO; today=
's=20
ZEO server does keep all storages open.

Also, not all storages permanently keep a file descriptor open.
