Right.  That should work.  Does `F' subscribe you to new nnimap groups,
or do you never see new nnimap groups?

The ChangeLog message for this is:

	(nnimap-open-shell-stream): Bind `process-connection-type' to nil, so
	that CRLF doesn't get translated to \n.

So binding it to nil fixes a real bug.  Is there no way to get rid of
stderr without using a pty?

The create group command is really meant to create the group on the
backend.  You can subscribe groups in Gnus, but if this has worked
before, it was probably an accident.  All the other backends create
groups in response to that command.

So you'll have to adjust your code to have Gnus subscribe the group
instead of calling out `*-request-create-group' to the backend.

You use IMAP as the interface to a SQL-based mail storage?

Anyway, for nnimap `F' just issues a LIST command.  Does a LIST in your
setup take minutes?
