This is inconsistent with the btree checking logic, which does no such check.  These two approaches should be reconciled, but there was apparently no agreement on this issue.

This next version, attached, has the acl checking and associated documentation changes split out into patch 0005, making it easier to review in isolation from the rest of the patch series.

Independently of acl considerations, this version also has some verbiage changes in 0004, in response to Andrey's review upthread.
