+1. POSIX Compliant. A good explanation is by Donald Lewin,
+ After a write() to a regular file has successfully returned, any
+ successful read() from each byte position on the file that was modified
+ by that write() will return the date that was written by the write(). A
+ subsequent write() to the same byte will overwrite the file data. If a
+ read() of a file data can be proven by any means [e.g., MPI_Barrier()]
+ to occur after a write() of that data, it must reflect that write(),
+ even if the calls are made by a different process.
