I don't know, IIUC it is just a short period (spell-checking one word)
in which other processes either do or don't see output, so I don't think
it matters that much to users either way.  It seems more natural to let
other processes make progress, because why not?  But again, either way
works for me, since both let us reconcile Flyspell with idle timers.
