I have been experimenting with the "task.h" classes in the Sun
distribution of C++ 2.0.  I have been able to create tasks which
are happy to share the CPU as true coroutines.  I have also been
able to use the Interrupt class to catch timer signals in order to
implement timed delays for tasks.  However, when all tasks are 
blocked, waiting for an interrupt, the scheduler seems to hang
in an infinite loop consuming as much of the CPU as it can.  

Does anybody out there know how to fix this problem.  I would like
to use the task class, but cannot afford to have a process eat all
the available cpu.
