For Watson we support several different prologs including SWI, but we had
the most success in terms of speed and stability with SICStus Prolog (using
its jasper JNI interface).  SWI and SICStus support almost exactly the same
set of predicates so it's fairly easy to switch back and forth.

I do recall hitting some memory leak problems with some of the prologs, but
the latest version of SICStus is holding up quite well for us.
