which appears to imply that slapd calls the checkpoint function itself

Skip it - I found the answer. Howard explained it thus:

``In OpenLDAP 2.1 and 2.2 the checkpoint directive acts as follows -
*when    there is a write operation*, and more than <check> minutes have
occurred    since the last checkpoint, perform the checkpoint. If more
than <check>    minutes pass after a write without any other write
operations occurring,    no checkpoint is performed, so it's possible to
lose the last write that    occurred.''

And my timeline was:

Force a checkpoint at 10:17.  Update at 10:19.  Because fewer than
5 minutes had elapsed *since the last checkpoint*, no checkpoint is done.

Right, that's what I said. ;) And again, this will be addressed in 2.3 on a permanent basis. :)
