Comment (by jinmei):

 trac1792 is ready for review.

 It depends on #1791, which is still in review, but my understanding of
 the discussions for #1791 is that the review results won't affect what
 we should do for this ticket.

 the first commit is to merge #1791, and should be ignored for review.

 The next couple of changes up to aaf4fb3 are trivial (unrelated)
 cleanups.

 The next two up to 501c5f2 are a set up for testing the main feature
 of the branch, and 9b060a7 is the main code and the test.

 I also added a simple lettuce feature to check the basic behavior at
 the higher level.

 I don't yet plan to add a changelog entry.  We can add a unified entry
 when #1793 is done.
