Even a read from an already-in-memory buffer, or a write to a
delayed-write cache? Or a rewind request issued to a tape drive? Do
you want Sequential_IO.Read to implicitly include a dispatching point
before doing any physical read, or before returning to the calling
program, or what? And why make others use such a routine when you can
write your own IO wrapper that includes a dispatching point?
