I spoke to Michen.

There's really no need for more than one thread to use the new
ldap_cachemgr status change feature: one thread in nscd.

That's because per-user nscds are short-lived anyways.

Michen will look at the changes to make it so.

That will address all my issues about this feature.

Also, the change status notification feature is somewhat more complex
than I'd thought, since there's server up and down change notifications.
That means that if we had lots of client threads then we'd need
something somewhat more involved than the designs I described.
