[LAU] Very frustrating problem with JACK and exporting through mixbus

[Jason Jones]

Just an update on this...

I just created a full project with a combination of 39 tracks and busses
with A3, and with Jack2 everything exported just fine.  I haven't been able
to export anything but very small projects with mixbus and Jack2.  The
issue definitely seems to be related to mixbus, Jack2 and the size of the
project.
