The answer is "no", because it is necessary to run the preprocessor in 
order to fill the cache and record the file list that direct mode 
lookups use.

It might be possible if you wanted to run the cache in read-only mode, 
but that might not be very useful, and I don't believe there's an option 
for that now.
