Comment (by arma):
Replying to [comment:12 dgoulet]:
> The offending party is the `circuitmux_append_destroy_cell()` which
basically creates one DESTROY cell, push it on the cmux queue and then
flushes it with `channel_flush_from_first_active_circuit()`. That function
does MANY thins and among those, it writes the cell directly to the outbuf
if the `outgoing_queue` of the channel is empty (which turns out to be
ALWAYS empty...).
Does that mean the destroy cell is going out before the other cells, with
the new kist scheduler?
