I need a global variable in pd, which gets maintained to contain a pointer 
to which object is the currently running object. This needs to intercept 
all message-passing and all perform-calls. All it needs is update that 
variable.

When I get that, I can make a profiler that is much more efficient than 
the one I had made for GridFlow, if I can use SIGPROF or SIGALRM or 
SIGVTALRM. (Windows programmers will have to figure out what the 
substitute is)
