I implemented the above mentioned technique, which isn't much code
anyway. It reserves a memory lot big enough to fit in the whole
mapping, memorizes the address, free's the memory again and then uses
penalize deletes of open files?
(Incidentally, I've noticed this as well.)

Thanks for the explanation.

I'll look when I can, but since you mentioned there's obviously some room
for optimization, could you state the obvious as a lead for someone who
has the time?

it is broken.
CREAD appears to always be enabled but not indicated by tcgetattr or
controllable via tcsetattr right now. So, the test case above is not
indicative of the original problem.
To the OP, posting your code might be informative.

processing boards, SCSI drivers, etc.)
The PAE stuff discussed by Christopher Layne in this thread does, however,
actually need that much memory for testing.

Um..., don't these functions look backward to anyone else in that the test
for local cache initialization is not what gets returned. I know it
really doesn't matter functionally, but it sure looks confusing ;-).

Ok, after further investigation, this is a /3GB boot.ini flag interaction.
Unfortunately, this is a critical flag for our application, so all our
machines are configured this way. That is why I failed to realize
you just map the big region, then overmap the disk file without the map,
unmap, remap, remap?

overmap? -v please?
Posix symantics: mmap fixed region x, mmap fixed region y which is a
subregion of x where y replaces x's mapping.
