logfile stops getting updated after first client exits.

```
What steps will reproduce the problem?
1. start the logging server.
2. start the test client.
3. stop the test client.
4. restart the test client.

What is the expected output? What do you see instead?
I expect logging to continue as normal after restarting the test client.
instead, the web UI continues to update with new log messages but process.log
never gets updated after the first client quits.

What version of the product are you using? On what operating system?
running SVN r8 on ubuntu 10.04. w/ twisted 10.0.0

Please provide any additional information below.
