Subject: Minor changes in the test program.
X-Git-Url: http://git.meshlink.io/?p=utcp;a=commitdiff_plain;h=7cfc0ef57625f1dcc443c811c0eff3b99f915f8f

Minor changes in the test program.

- Add one to the timeout in milliseconds, to prevent roundoff errors from
  causing us to busy-loop unnecessarily.
- Log what we are polling for and what the timeout is.
