Sounds reasonable.

It's possible that the "rewrite" might not be all that major. Setting
the scheduling class for a thread is fairly easy. Making sure it
doesn't call any non-realtime-safe system services is harder. If you
need to read or write a log file on disk, you'll almost certainly need
a multithread solution similar to what we do for audio capture or
playback. Disk I/O is definitely *not* a realtime-safe operation.
