Hello again Python programmers,

	Final update on my Python 2.7.3 build issues.  After much insanity I final=
ly used a process sniffer when running Python and tracked down that because=
 of a path environment variable and the stupidity of Microsoft, Windows was=
 loading another python27.dll rather than the one in the directory with the=
 python.exe that I built, thus rendering my former tests useless.  Sorting =
this out using the .exe.local trick, I was able to re-test everything and c=
ome to reliable conclusions.  Based on performance results, it is without a=
 doubt in my mind that the Python 2.7.3 precompiled binaries in the MSI are=
 a PGO build.  I can now build my own binaries with the same performance as=
 the released precompiled binaries.  And on my machine at least, these PGO =
built binaries do perform 30-36% faster than a normal release build.  Usefu=
l information if you're doing your own Python builds.  I'd still like to se=
e Python start including some thorough build documentation on each release,=
 but I'm certainly not going to be holding my breath on that.  ;)  Cheers.

Sincerely,
Arah Leonard
