Render() and "Audio engine overloaded, resetting"

Hi List,

I have googled around a bit trying to find this, so hopefully this is a reasonable
thing to ask and not an example of poor googling skills.

Are there specific guidelines for how much processing can be done in Render()
in an SynthNote of AUInstrumentBase()? 

I understand the point is to do as little as possible, as quickly 
as possible, but are there rules of some kind? Or at least 
guidelines? 

Can the limits be measured solely in time? e.g. spend 10 ns in
Render()?

Is anything off limits? File IO I guess is cool. From what I can
tell, allocating memory was not a good idea.

Does Attack() cause overloads? 

It looks like GarageBand is less forgiving than Logic, in terms of
overloading. I haven't tried other hosts.

If there is some document about this hidden somewhere, I would
be interested to read it.

THanks!
