[Ardour-Users] A3: Silence and session load weirdness after re-open

[Thomas Vecchione]

Exactly how would you suggest this be handled?  I can see giving
notification that such a loop was detected possibly, but that is the extent
of it.  I certainly wouldn't want a feedback loop starting up and
destroying my monitors while I searched for what caused it.
