Okay. I managed to find a recursive fibonacci forth implementation which 
gives the following results for fib(28):

Latest SVN without patch: 37s
Latest SVN with path: 59s

So that works out as roughly a 60% increase in execution time just for 
adding the extra checks :(  This seems beyond even my limit of 
acceptability, although I have some ideas to work around this...
