Will do.

First things for Kontakt are in our wine. (1) You need a way to set 
thread priority without hitting the wine server. And (2) you need a way 
to do simple thread synchronization without hitting the wine server.

There's more going on, though, that is causing the latencies. And the 
output from cyclictest/ftrace is incredibly dense! It will be a slog. :(
