Sticky bit?

Depends on your definition of "'Unix' in general."  It doesn't apply to
SunOS 4.x, and possibly not to S5R4 as well; SunOS 4.x doesn't interpret
the sticky bit as meaning "keep a swap image around" (it's not
necessarily an "image" in any case; pages paged in directly from the
file, and not copied-on-a-write, do *not* have copies in swap space).
