The FHS says we can create directories under /var/run that are
application specific.  It also says that all files should be
removed or truncated.  It does not say anything about directories
being removed.

On the other hand, about /tmp it very clear and says:
"Programs must not assume that any files or directories in /tmp
are preserve between invocations of the program."

If I create a directory in /var/run, I expect it to stay there.  And if
I can't expect that, I'd like to see that documented somewhere.
