I said it could be a problem if a low priority hold a resource for
longer than it really needs will slow down a high priority task.
When I said about the CS version and renicing it, I thought it will let
the high priority task to get a lock in the resource earlier than the
low priority one. But of course once the low priority get the lock it
will hold it for a long time than it would be without the renice, of
course causing trouble. :-(
Thank you for shed some light on my dumb thoughts :-)
see you !
