How could you implement a busy lock field in the file to indicate the file was busy being updated? or busy being read? In RAM you have test and set locks to check a value and set the value in one atomic operation. How could you simulate that without test and set hardware on the SSD? You can't very well share a RAM lock between separate jobs. -- Roedy Green Canadian Mind Products http://mindprod.com One of the most useful comments you can put in a program is "If you change this, remember to change ?XXX? too".
