Status bit for overloaded streams

[BigEvilCorporation]

Currently a busy stream will just cause slow playback, it would be handy to know if this happens via a status bit/error code for debugging and QA

Yes, I've noticed some slow down/speedups with a stream of pitchbend commands for FM tom toms. Maybe this will resolve the issue?

That won't solve the issue, the only thing that will solve the issue is making Echo faster :P (ironically, if I do the 2ch PCM thing, it'll get worse, not better :/ but every composer asks me if it's there probably because they heard Ristar does it so they assume everybody can do it)
