Hey Nico,

Take a look at the reference manual for Swarm, where it says
in the Collection protocol:

- (void)removeAll
    The removeAll message removes all existing members of a collection and
sets
its
    member count to zero. The collection then remains valid for further
members
to be
    added. This message has no effect on the objects which might be referenced
by any
    removed member values. If resources consumed by these objects also need to
be
    released, such release operations (such as drop messages) can be performed
prior to
    removing the member values.

This means that what you actually want to do is drop all
the elements in the map then drop the Map, itself.  Not
only do you have the objects floating around out there
after you do the removeAll, but you also reset the map
pointer without dropping the previous map.
