Since I had over a dozen vertical market apps out there (real time,
point of sale stuff)  in the hands of hundreds of users in North and
South America, the shit was hitting the fan very rapidly.

I tried all of the available patches and each either caused CPU
lockup, run-time errors or corrupted the integrity of the one
millisecont delay() functon in the CRT unit.

I wound up having to patch the assembly code in the RTL myself in
order to keep my software working and maintain timing accuracy.  The
patched code adds another 8 bits to the counter so PC's will have to
be 256 times faster before the problem reoccurs.  Software compiled
with this patch is running all day every day on fast PII's in over 50
locations and has been tested successfully on the PIII.
