summon -all hung after downloading "present", so I turned on debugging and
resummoned all to find that there was some confusion on profile-gnome-platform
spell as it seemed to think there was already a lock on it.

This confused me, so I summoned profile-gnome-platform to see if it hung, and 
it
didn't.

Then I figured, why not try listing it twice.  That hung it.

Then I tried listing profile-gnome-platform next to thttpd, that worked.

Then I tried listing thttpd and thttpd, that worked.

I can only guess that profile-gnome-platform tried to be summoned twice as a
result of summon --all trying to summon all the installed grimoires and
duplicating the spells to download.

Perhaps summon doesn't give up its lock after each summon that is a virtual
spell (no download/summon needed), causing lock contention afterwards.  That's
what it appears from the debug.out log, but I can't really tell because 
there's
no entries for unlocking anywhere -- perhaps we need some debugging added to
show that we're unlocking a certain resource.  I see lock_file and 
unlock_file,
but nothing about unlocking after a trylock_resources.  I don't think we're 
not
unlocking at all because otherwise thttpd would have never summoned twice 
correctly.

Rather than attach the log, I invite the reader to duplicate the test cases
above with debugging enabled ;)
