The default value for this was 64K. We increase this by a factor of
10 to 640K to prevent data loss when using fast serial interfaces.
Since this value is only a maximum limit for allocation and isn't used
by default, this change has minimal effect on systems with slow interfaces.

Is there any reason for this _limit_ to be as small as 64K?
thanks,
martin
