After thinking about it some more, I believe that there are two kinds of tasks
that may need to be executed at the end of a transaction:

    - commit tasks
    - cleanup tasks (in which I include "cache updates")

probably "commit tasks" should be FIFO and "cleanup tasks" LIFO.  "commit tasks"
are executed only if we choose to commit, but "cleanup tasks" are always
executed.
