Answer 1

A true blocking ThreadPoolExecutor has been on the wishlist of many, there's even a JDC bug opened on it. I'm facing the same problem, and came across this: http://today.java.net/pub/a/today/2008/10/23/creating-a-notifying-blocking-thread-pool-executor.html

It's an implementation of a BlockingThreadPoolExecutor, implemented using a RejectionPolicy that uses offer to add the task to the queue, waiting for the queue to have room. It looks good.
