Oh, fcntl has already a F_FULLFSYNC constant, so we can use like fcntl.fcntl(fd, fcntl.F_FULLFSYNC) in Python.

Hum, it does flush the file on VMS using fsync(), but on Mac OS X, it does just set F_FULLFSYNC flag using fcntl. It doesn't call fsync() explicitly. Does mmap() "call fsync()" implicitly?
