#
# 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_waits(thr1, thr2, ...) do |t|
#     STDERR.puts "Thread #{t} has terminated."
#   end
#
#
#   th = ThreadsWait.new(thread1,...)
#   th.next_wait # next one to be done
#
