I don't think it is ready for 10.1.2 yet. Ole pointed out to me that
after the patch was committed, the Tinderbox test on Solaris 10 x86
has failed twice.

I guess rawStoreDaemon tries to access one of the variables I set to
null in ContextService after the the ContextService is stopped.
Although this has happened twice with the Tinderbox test, none of the
nightly tests (six platforms) have had problems with the patch.
