Interesting. I am using 1.0 with the mw-diffs and I get absolutely
_zero_ SILO overflows at 38.4.

You may look at two things: The mw-diffs need an option in the
config file to defer interrupt level 6 (which is what makes serial I/O
reliable). You also want a much larger buffer for the serial interrupt
than the default. If I remember right this is a config option too.
