yes the reporter is correct.

the suggested chdir happens in the subprocess.

however, that only works on posix systems:

windows currently uses popen2/3.  (see issue1535504 for another issue
with that).  switching to subprocess and passing in cwd would fix it.

and non-posix non-windows (what is that?) uses execfile to run the
script in process.  we can't fix that one, nor should be bother.  what
is a non-posix non-windows system that needs to run a cgi http server??
