File permission is not really in the I/O turf. MPIO is defining how
to move data between files and memory. File permission belongs more
to the filesystem operation. If MPIO must say something about file
security, how about this:
"When a file is created, the implementation, if possible, should set
its permission to accessible by owner only."
Applications that need to do more would have to either do it
via the INFO or some other system calls or post-processing.
