Hi,

I suggest that this special case be made into a new function, named 
callout_drain_async() inspired from projects/hps_head and that r287196 
be backed out, so that callout_stop() works like before. See:

https://reviews.freebsd.org/D3521

And that the following patch be MFC'ed to -current from 
projects/hps_head after D3521.

It should close the race in question.
