Keep in mind that the newer meanings of the sticky bit, such as
making a directory "append-only," may not apply to many UNIX systems.
My SCO Xenix 2.3.2 will not recognise a sticky bit on a directory.
On my 286 system its only use is to keep text segments in the swap
space.  On the 386 versions, since they use virtual memory, not
even that applies.
