Good idea.  The rtc latency test (1024) has a max latency of 1.7ms with
all but 5 samples occuring a fraction of that latency.  (bdflush?)

Anyway it looks like it's the maestro3 driver.  Min latency is still 8.3ms
with either OSS or alsa's OSS emulation.  I get horrible overruns with
any buffers smaller than 8x512.  I'll see about the driver.
