They also have the 1940 census coming out and the DNA project to be announced, so there is a lot going on.
People may also be able to find your tree through hints which may be more up to date. I see changes in my own trees in hints, right away. Also, they may be able to access your tree through your profile here on the message boards. Some people have their trees listed on their profiles. I don't know if accessing that takes you to the most recent tree or an older version. Of course, the above doesn't change the fact that it would be nice to get the indexing updated.
I agree with ginglish1 that is is "important that ACOM has their site stable before they do reindex".
