You get "Not documented as a symbol" on any lookup.  This is unchanged
actually, since if there's no manuals at all available then nothing
goes into the cache.

The bad case is when there's a missing manual in the middle of the
list, every lookup into a manual past that gets the message and delay.

The sit-for is the annoying bit.  I don't know that a message every
time adds much, but it doesn't hurt.
