Uhhh..  On my A3000, this slows ftp transfers down to 100...150 K/s and
I definately _do_ worry about it.  I didn't see this with the old ed
driver, so I can't understand what's happening with the new one.

The problem happens with 16 K buffer RAM.  The CPU has more than 10 ms
to read the buffers before an overflow occurs.  I think it _should_ be
able to do that (a 25 MHz 68030 in my case).
