OK, ThreadPool become a block like any other, in that there would be XML
in assembly.xml and config.xml. Fine by me.
You think that a lot of "core" existing code is not using
org.apache.avalon.excalibur.thread.ThreadPool and should be.
Would we have a default Phoenix/Cornerstone block that implemented
thread-pool and patched it's calls through to the excalibur version?
Could/should the excalibur version continue to be used directly by
blocks or should everything migrate to the block based ThreadPool?
(hoping I have understood correctly).
