It seems that mmap always fails on NT if the file has been opened by
some other process.  I suppose it has something to do with the file
sharing options, which probably default to no sharing at all.  For
instance, I do not know if it is possible to mmap the same file into two
processes simultanously; perhaps somebody wiser than me can tell. You
may want to check that this is not the cause for your problems.
