Under Unix with a normal unix filesystem, the filesystem stores
attributes about each file.
With FAT filesystem there are no such attributes stored - cygwin has to
figure them out.
In particular, if a file is executable or not has be to guessed at by
reading
the first few characters of the file. So, cygwin has to open each file
to
determine this which doesn't happen under unix.
