Fixed. In any case, I compiled against 3.0.1, as it was what I had
locally. I'll try 2.6 as well, but if you encounter any more bugs,
please mention your platform and Python version. I'll have to do
rebuilds and rereleases of 3.0 and 3.0.1, so let's hope there's not
any more :-)
Cheers,
Richard.

Log:
Fix for strange application restarting bug, where in some
circumstances an exception was compared to SystemExit, and if it
matched, the application was asked to exit. TaskletExit is a subclass
of SystemExit, which means that when it is raised, if it hits this
execution path, the restarting occurs.
