-           - on nfs it is not possible to mmap a file if direct I/O is enabled on it;

-           - the performance impact of blindly turning off directio for each mmap 
-             is roughly 15%;
-           - directio is documented on recent official docs (April 2003) to cause data 
-             corruption, system hangs, or panics when used concurrently with mmap
