Aleksey Shipilev updated HARMONY-5918:
--------------------------------------

    Attachment: pack200-threading-threadpool-v1.patch

pack200-threading-threadpool-v1.patch
Early prototype, based on java.util.concurrent.ThreadPoolExecutor. Though it contradicts with requirement for having 1.4 source, it's enough for prototype. This patch depends on HARMONY-5916.

For unpacking scenario:
 gives +16% boost on 2-core ThinkPad T61p
 gives +50% boost on 8-core Xeon X5350
