Re: Backwards typing under load

I've seen the same problem with MSK's ksh, under heavy loads.  I'm not sure,
but I think it was under CPU loading, not necessarily interrupt loading.
I would n't be surprised if the COMMAND.COM (or whatever) keyboard interrupt
handler actually builds a stack of pending reads from some sort of fifo, and
pushes them into the event queue reversed when they pop off the stack.
