One example I know about: R for windows is compiled using mingwin, but can be used without having mingwin installed. (It installs cygwin1.dll or something, b ut most people know nothing about that).

It is not search_doc itself which takes so long time. I have a fast machine
and that one is only a few seconds. But when I click on one of the files shown,
then opening it in the browser takes an unreasonable long time.
