First i thought that you are addressing the use case "read, interrupt,
seek, read". (As far as i know and remember, there's no guarantee this
use case would work, but somebody uses it happily.)
But re-reading you i see you mean something else. Could you please
describe one or more cases where such feature would be needed? It
would be great if you provide some code and/or setup instructions, so
we could check the problem and the effect of these changes.
