Could you please elaborate on how my
proposed patch could possibly affect
that? It basically doesn't do anything
at all except providing one more callback
for what would otherwise had to be done
in a trigger() callback anyway.
If there is a race with that patch, then
I pretty much suspect it was with an old
code too. I can't imagine any possible
change. What have changed?
