In the disto no-halt I have, there is a 256 byte buffer in the disk path 
that serves as a rubberband for the disk traffic.  That buffer can be 
read or written to while you are typing, without missing a keystroke, 
usually a complete read or write in between your keystrokes unless you 
are really fast, but can be interrupted by your keystroke too.

I expect other no-halt stuff works similarly.
