Minimal testing has shown that a 4 page tsb is a nice sweet spot for current
work loads. It tapers off after that as gcc's working set generally just fits.
compiling bin/csh:
TSB_PAGES = 2
213.33 real 77.59 user 110.01 sys
TSB_PAGES = 4
116.43 real 75.78 user 19.16 sys
TSB_PAGES = 8
119.27 real 76.38 user 18.12 sys
Testing by: tmm
