[PD] abstraction creation audio engine start

just a sidenote, but you do know about [switch~] to turn off audio
processing in a subpatch/abstraction, right?

i used to have a patch that had about 3000 dsp building blocks (oscillators,
filters, waveshapers, eq, effects, etc), and the patch just switched on each
part when it was called.  in this way everything was loaded at startup, and
pd didn't need to create any new objects in realtime.

i just had to be careful with blocking messages from going into [vline~]
while the patch was switched off, because they started to make cumulatively
longer and longer queues that got completely re-written every time a new
message was sent.  this was a known issue last year, so maybe it has been
fixed for newer versions of pd?  i still treat vline~ with caution though,
just to be safe.
