i think its worth considering the words of the boost::signals2 people
on this matter. signals2 has a much nicer, safer and more easily
thread-safe model for managing connections. they still provide a
"trackable" base class but its use is deprecated since they could find
no way to make it acceptably efficient & thread-safe.

i recently converted the entire backend of ardour from sigc++ signals
to boost::signals2, and in general i find the signals2 connection
management model MUCH more satisfactory.
