-#  feature:
-#  provides synchronization for multiple threads.
-#
-#  class methods:
-#  * ThreadsWait.all_waits(thread1,...)
-#    waits until all of specified threads are terminated.
-#    if a block is supplied for the method, evaluates it for
-#    each thread termination.
-#  * th = ThreadsWait.new(thread1,...)
-#    creates synchronization object, specifying thread(s) to wait.
-#  
-#  methods:
-#  * th.threads
-#    list threads to be synchronized
-#  * th.empty?
-#    is there any thread to be synchronized.
-#  * th.finished?
-#    is there already terminated thread.
-#  * th.join(thread1,...) 
-#    wait for specified thread(s).
-#  * th.join_nowait(threa1,...)
-#    specifies thread(s) to wait.  non-blocking.
-#  * th.next_wait
-#    waits until any of specified threads is terminated.
-#  * th.all_waits
-#    waits until all of specified threads are terminated.
-#    if a block is supplied for the method, evaluates it for
-#    each thread termination.

-# This class watches for termination of multiple threads.  Basic functionality
-# (wait until specified threads have terminated) can be accessed through the
-# class method ThreadsWait::all_waits.  Finer control can be gained using
-# instance methods.
-#
-# Example:
-#
-#   ThreadsWait.all_wait(thr1, thr2, ...) do |t|
-#     STDERR.puts "Thread #{t} has terminated."
-#   end

-# Documentation comments:
-#  - Source of documentation is evenly split between Nutshell, existing
-#    comments, and my own rephrasing.
-#  - I'm not particularly confident that the comments are all exactly correct.
-#  - The history, etc., up the top appears in the RDoc output.  Perhaps it would
-#    be better to direct that not to appear, and put something else there
-#    instead.
