Indeed, it seems there isn't a nice, neat interface to ask the clock
if it's still running or not.

An alternate way is to add a dependent to the clock. It will broadcast
a \stop message when it's stopped. Your object can receive that
message and remove routines immediately when the clock stops, instead
of "at some point."

t = TempoClock.new;

~tDeathWatcher = SimpleController(t).put(\stop, { "t stopped".postln;
~tDeathWatcher.remove });

t.stop;


My ddwGUIEnhancements quark adds a method to TempoClock:

    isRunning { ^ptr.notNil }

I suppose I should put that in ddwCommon -- it's in ddwGUIEnhancements
to support TempoClockGui.

I can't think of a good reason not to add this method to the main class library.
