Understanding sticky bit in linux

1) Sticky bit was used on executables in linux (which was used more often)so that they would remain in the memory more time after the initial execution, hoping they would be needed in the near future. But since today we have more sophisticated memory accessing techniques and the bottleneck related to primary memory is diminishing, the sticky bit is not used today for this. Instead, it is used on folders, to imply that a file or folder created inside a stickybit-enabled folder could only be deleted by the creator itself. A nice implementation of sticky bit is the /tmp folder,where every user has write permission but only users who own a file can delete them. Remember files inside a folder which has write permission can be deleted even if the file doesn't have write permission. The sticky bit comes useful here.
