      Description

      In Jenkins thread dump I can see something like this:

      pool-4-thread-18865

      "pool-4-thread-18865" Id=375223 Group=main TIMED_WAITING on java.util.concurrent.SynchronousQueue$TransferStack@1412ebc5
      at sun.misc.Unsafe.park(Native Method)

      pool-4-thread-18866

      "pool-4-thread-18866" Id=375224 Group=main BLOCKED on com.thoughtworks.xstream.mapper.AnnotationMapper$WeakHashSet@41deb94c owned by "pool-4-thread-18870" Id=375228

      My guess is, that these pools are the tread pools of the executors asssociated to channels as constructred e.g. in Launcher#main

      Would be nice, if theses pools/threads would have non-generic name - i.e. names which make it obvious where the threads come form
