 # On Windows, Psyco shortens warm runs of build/gyp_chromium by about

 # maxes out at about 158 MB vs. 132 MB without it.

 # Psyco uses native libraries, so we need to load a different
 # installation depending on which OS we are running under. It has not
 # been tested whether using Psyco on our Mac and Linux builds is worth
 # it (the GYP running time is a lot shorter, so the JIT startup cost
 # may not be worth it).
