It is not documented and unpredictable. In theory the latency can be 2
seconds or 30 minutes. I don't even know, if the system will crash if
you try to do that kind of stuff from inside a real-time thread.
And there seems to be conflicting reports on multi-threading. A
multi-threaded Audio Unit: kosher or not?
It probably conflicts with the host, which always does multi-threading
to offload the plugins (usually: the channel strips) onto different
threads. I wouldn't do it.
