Hehe, I can see that this does something that looks very similar :-)

I think a DeferredQueue is a bit more general than my code -- I think
you need some code in addition to a DeferredQueue in order to obtain
what I want: limited parallelism.

In particular, I guess you need to catch the QueueUnderflow exceptions
and then somehow know when it is time to call get() again.
