There is a chance that we'll exhaust TLS slots, and that might only happen when
enough features are run at the same time (and not have popped up in unit tests).
Getting messed up (and not realizing we've exhausted this list) seems like a
very Bad Thing (TM), and hence worth a CHECK.

I'm fine with this, as it should only happen when hell has broken loose, or when
the logic is hosed (and we didn't ask for a slot first).  I believe we should
have caught such in unit tests... so this can be a DCHECK (I think).
