syslogging to a fraction of its former self. Actually, its mostly been
moved under if (verbose) tests. Instead, just syslog the number of
bytes returned for each request.

Added a signal handler to change the verbosity of a running tmcd.
To turn on verbosity:

	kill -USR1 `cat /var/run/tmcd.pid`

To turn off verbosity:

	kill -USR2 `cat /var/run/tmcd.pid`

You can send the signal to individual children, but that would be
silly and pointless.
