      Both in tokenize (QStringTokenizer, split(), tokenize()), as well as other functions (count(needle), basically anything that loops over indexOf()), we repeatedly build BM tables for a one-off search and then re-create them for the next loop iteration.

      This is clearly wasteful, so we should identify all these issues and fix them.
