qrunner chokes on huge qfiles directorys

[Bug Importer]

A out of diskspace situation created a few hounderd *.db files with no
*.msg files. qrunner exits after processing N files. Since it skips *.db
files while processing it should skip them too while counting when to exit
to avoid deadlocks.

Erm. I guess my patch better ilustrates what I mean:

A slightly different patch will be included in Mailman 2.0.1 which will fix
this problem.
