Useful, yes.  Harder than it looks, probably.  I tried to mock up a
version of this years ago for a project where I needed it, and ran into

Anyway, if it could be made to work, this is extremely useful for any
application which needs queueing behavior (with is a large plurality, if
not a majority, of applications).
