The butler doesn't do async I/O so at least that is the wrong tree.
But it would be nice to figure out why/where the pausing is occurring.

So the real question is, why not turn on software monitoring for all
tracks, do the jamin routing with an insert in the master bus, and
route the output of the master bus to a new recording stereo track.
Then everything is done in realtime as you do it.  No render step
necessary, just combine the audio files from that final track with
another tool, and export the TOC file only with ardour (no audio).
