This is not necessarily a given. Nothing is cast in concrete that MSS3a
*has* to be wired to the 1.4.X stream. We do tend to say this internally
in the storage-devel group, if only to limit the usual wankage of:

	1. problem?
	2. update to -current first!
	3. (two weeks of merging). Goto #1.

If there's a showstopper technical reason that is impractical to get
around, resync'ing with 1.5 may be better. And this complete spasm
occurred a year ago wrt 1.3 as well.
