The downside to this is that there is a bug in the NT/2K/XP command
interpreter which will prevent redirecting from stdin in that case.  That
is:

C:\Tmp>type x.py
import sys
print sys.stdin.readline()

C:\Tmp>echo 123 | python x.py
123

C:\Tmp>echo 123 | x.py
The process tried to write to a nonexistent pipe.

C:\Tmp>python x.py < x.py
import sys

C:\Tmp>x.py < x.py

C:\Tmp>
