Subject: [PATCH] thread: print error for io_devices at lib fini

All io_devices should be unregistered before the
application exits.  If not, print an error message
for each io_device that still exists.

Eventually we may want to assert() if any io_devices
are found, but for now we'll just stick with the
error message.
