[PD] loadbang in dynamic abstractions

I unfortunatly found many issues with things not happening in the
correct time. Well that is to say when you dynamically create an array
of objects the time between the message being send and the object
actually being ready to receive messages is not 0ms. I can't remember
the delay I needed, but indeed some abstractions would not get the bang
message if I sent it immediatly after the message to create the last
abstraction. This is on OSX, which has had some GUI issues in the past,
could be related.

Oh and this is also because I'm not creating my whole dynamic patch with
one message, but multiple messages. (This is because I'm creating one
abstraction for each file in a directory)Also the number of files is
indeterminant so I can't create one message to do it all...

I guess the best way to test if the last object is done would be to have
it send a message "I'm done!" to the parent patch and then we know all
the abstractions are ready... Maybe I'll do this...

Back to replacing my TOTs with PYs.
