Each read and write is mapped to a single request, so the usual.
I'm still a little unclear on this. Disabling the function ought to
have much the same effect as changing the config or altsetting: Writes
to endpoint files should be flushed and reads should be terminated.
Otherwise you would end up sending stale data to the host or reading
data that the daemon isn't prepared for.
You may have a point here. I'll try to prepare a patch over the weekend.
It looks like our patches are going to have dependence.
If you send yours this weekend, I'll wait to send new version of this
patch of mine on top of yours.
