  The biggest problem is that when rendering is turned on, GEM traverses the
entire hierarchy to build a network behind the scenes.  This means that once
the hierarchy is built, no messages go through the normal pd connection
mechanisms.  In other words, if the objects cannot establish a connection
when rendering is turned on, they will never be connected once you are

  The other problem is that an external mechanism controls the running of
the hierarchy (GemMan), so individual objects can't stop the processing.  It
could be possible to modify gem to allow for an "abort", but it would take
some low level changes.

  I will think about this a bit more, though, and see if there might be some
way to deal with it.

Later, Mark
