Hi everybody (and Happy Holidays),
The general consensus is that program code is automatically shared by the OS
and that the sticky bit is no longer needed. Its use was to prevent some
programs from being removed from the swap after their invocation so that they
could be fetched more rapidly at the next invocation. Since Sun pages programs
directly from the filesystem, the sticky bit is no longer needed.
