A recursive mutex is dangerous. We really should understand why it is needed. I
think it can be avoided. The original developer avoided it in one scenario
using demux->priv->exposing. Maybe we can do this here too, for the particular
scenario that caused you problems.

I can't identify that place. Can you recall the scenario? Don't need to prove
it, just describe it.
