I've not looked at the code, but if we know the sink index by this stage
(I'm not sure we do?) then yes that could be helpful.

Pierre will probably know if this is practically useful tho'. I suppose
in most cases testing and probing will be done with only one sink anyway
so there is no doubt which one owns the thread :p
