Well today I completed a build of OpenSTA without using the STLport
at all, but still using the latest PSDK.  I had to make a few
modifications and was left with plenty of warnings but it does build
and appeared to basically work...

I then ran the benchmark we have been discussing and was blown away
with the results:
                      1.4.3  STLport4.6.2 No STLport
                     Release    Build       Build
      /  URLENCODE1    5.51      1.82       0.68
VSTATE1  URLENCODE2    7.21      2.17       0.81
      \  URLENCODE3  180        70.1       33.4

      /  URLENCODE1    1.26      0.40       0.14
VSTATE2  URLENCODE2    1.38      0.42       0.15
      \  URLENCODE3  189        68.2       36.2

I've double checked this and added debugging to the script to make
sure the encoding was actually being done - and it seems kosher.

I think this shows a fairly clear path forward at this point,
obviously lots of testing needs doing.  I'd also like a 3rd party
to replicate my results.  Any thoughts on these results or what our
path forward should be?
