Daniel, thanks again for bringing up this example! It turned out that quite
a lot of the difference in performance was due to an inadvertent space leak
in the text search code. With a single added bang pattern, the execution
time and space usage both improved markedly.
There is of course still lots of room for improvement, but having test cases
like this helps immensely.
