hi Thomas,

unless a message is delayed explicitly via a clock, there is no point
in self-messaging, because sending a message in Pd is implemented as
an immediate call of a method (there is no message queue).

Another way is to schedule triggering of the sub-methods in a method
registered in the dsp chain.  This only applies to certain actions of
tilde objects -- a nice example is sfplay~ external (from ggee or zexy).
