[PATCH 1/3] lei: safety fix for multiple WQ classes

[Eric Wong <e@80x24.org>]

For commands utilizing multiple workers, this simple change
generalizes the persistence mechanism and and prevents
lei->dclose from causing script/lei to exit if there are
still in-flight workers.

This ougth to prevent read-after-write consistency problems that
occasionally manifest in scripts (e.g. test cases) but usually
go unnoticed in normal use.
