Create a new instance, set the test variable.
Answer whether the condition will block or not (boolean).
Wait until the condition is true and signalled. This only works in a Routine. This method yields a symbol (\hang), so that the clock doesn't reschedule the Routine.
c = Condition(false); fork { 0.5.wait; "started ...".postln; c.wait; "... and finished.".postln };c.test = true;c.signal;Wait for value time, regardless of test. This only works in a Routine. This method yields a symbol (\hang), so that the clock doesn't reschedule the Routine.

Resume threads.
