After the above I tried a couple of things, like printing l.held (with
no further attribute).  These also hung for a few seconds and I
interrupted with ^C.
Eventually it failed with an error about not being connected to Mailman.
I thought Mailman had crashed, but when I tried shutting down Mailman
using bin/mailman, it seemed to shut down normally.
