Interesting, non-recursive was slower than recursive. I suppose I can see

many directories do you have?
It is 19 make re-executions. The reason non-recursive is slower is that I
haven't had a chance to optimize it yet. I actually expect it to be faster
than recursive (for obvious reasons).
It just occurred to me:
If the re-exec's are occurring due to the dependencies file generation, then
converting to the more advanced way of generating dependencies files will
eliminate the 19 re-exec's.
So, try to optimize away the re-exec's first (this should be the most bang for
the buck), then redo the timings. My guess is that the differences will
dwindle a lot.
Otherwise, if you're running on Linux, try running Valgrind to see where the
slowdown is.
