[DM] Worker threads leaking

[Andreas Jung]

2. Introduction

With Zope 2.11, worker threads seem to be leaking.

I expect that uncaught exceptions are responsible for these leaks. Python will in this case catch the exceptions, write a message to stderr and abort the thread. In our production environment, stderr is redirected to /dev/null and it would be necessary to change the instance recipe to control the redirection (good old days with their easily modified shell scripts....).

3. Feature

Catch exceptions that could cause a thread's death and log them.

4. Example Use Cases

Try to avoid the worker leak that currently affects our production environment.

I don't think "Fix Released" is an appropriate status for something that is still on a branch.
