If read-subvolume or read-subvolume-index is somehow not getting through,
then we're back to the read-hash-mode default - which does *not* try to
use round-trip-time measurements. Still, it should give different
results for different files.

It's hard to see how that would be the case, since the code to set
read_child based on first-to-reply seems to be *missing* in the current
code. :( What version are you running, again?
