It's just impossible to fix them without having a bounce buffer.
The only way would be to not use the hardware. I guess
we can find out how many people still use floppies and other
such hardware by having it for some time in -mm*.
But I reserve the right that if this thing becomes a FAQ - e.g.
various people set the option wrong and break their systems
to rip it out again. I'm not interested at all in patches that increase
the bogus bug report rate.
