I was about to report a bug but then I found bug report "[ 1100235 ] Scripts 
started with CGIHTTPServer: missing cgi environment" which is actually 
caused by "[ 1110478 ] os.environ.update doesn't work".  They are fixed with 
a patch in 1110478.  I still have to try it.  I do like the alternate 
solution proposed by the originator of 1100235 though.  I also thought that 
CGIHTTPServer should use the new subprocess.Popen class instead of popen2, 
popen3 and popen4.
