This may not apply to you, but if you try writing to disk with a DOS call
(which is the easy way to access the file system) in the background, it will
not behave. DOS is extremely non-rentrant (sp?) and does not like people
trying to do two things at once. You will have to do something to be sure
that DOS is not doing it's thing when you want to flush your buffer. I would
guess that grabbing INT 21 (ugh :-() may help but some Guru here may know a
better kludge.
