Ah, right, that's another thing.  The hosts do.  In reality most

probably are already aligned, but the weird cycle size thing some do

circumvents that, of course.
As it happens, none of this buffer size stuff is actually guaranteed by

Jack, which would need to happen to make implementing buffer size

guarantees actually possible.  IIRC in Jack1 it is always true, but not

always for Jack2.  If so, there needs to be Jack API for the host to

know what it can actually guarantee.
