Hi Igor,

Thanks for the reply.  However, I've confirmed that the
boost::asio::deadline_timer object still exists.

In examples I've found for repeating timers, that the timer is re-scheduled
within the handler itself.  In my case, the timer is re-scheduled sometime after
the handler has run.  I wonder if a timer cannot be re-used this way?
