Ccing the mailing list to see if someone can come up with a nice way
to solve this problem. =)

Excellent idea. =) Closing files immediately after planner-update-task
will result in lots of churning, though. Maybe we can do it the way
the calendar does it? I know there's similar code in
planner-kill-calendar-files. Before saving, we can make a list of all
open planner files, and then restore this list after all the saving is
finished.

Okay, think it's fixed in dev...
