Thanks. The problem with using sat-solver for matching the filelist is that
it is targeted at queries resulting from interactive use (user searching for
something via a GUI). It wasn't designed for these kind of automatic queries,
especially searching in filelists isn't particularly fast (it needs to
construct each entry from a directory list and a basename just to run the
regexp on it).

We could optimize this a bit further as a special query type (where directory
and basename are given separately) but I wouldn't hold my breath. For the
time being I either would make this feature optional (and I think it's
basically a nice feature), or implement a cache just for the programs that
could be looked up faster.
