Surely the upper bound here is just an upper bound and we're essentially
just saying that "anything over minimum is fine" here?  Though now I
look at the implementation it seems it's doing something entirely
unehelpful and actually trying to delay for the longest possible time
which doesn't seem like what we want or what the usleep_range() API
would suggest :(
