- * This is mtab locking code test for:
- *
- *	- performance (how many concurrent processes)
- *
- *	- lock reliability (is possible to see corrupted data  if more
- *	                    concurrent processes modify a same file)
- *
- *  The test is very simple -- it reads a number from locked file, increments the
- *  number and writes the number back to the file.
