Summary: popen3 on windows loses environment variables

Initial Comment:
see the following test code:

#test_popen3_1.py
import os
FILENAME='c:\temp\test_popen3_2.py'
os.environ['FOOBAR']='foobar'
print os.environ['FOOBAR']
fs=os.popen3("c:\python24\python -u %s"%
FILENAME,'b')
print fs[1].read()

#c:\temp\test_popen3_2.py
print "from test_popen3_2.py"
import os;print os.environ['FOOBAR']

Running test_popen3_1.py is expected to print out:
foobar
from test_popen3_2.py
foobar

But it doesn't print the last foobar. It correctly prints 
out when run on python 2.3.

If the FILENAME is set to a relative path, as when you 
are in the c:\temp directory and the FILENAME is set to 
test_popen3_2.py, the code works correct.

Tests run on windows XP, SP1.

This bug is related to the cgi bug #1100235.

Sorry. I got confused. When FILENAME is absolute, popen3 
loses the environment variables, whereas it is relative, 
popen3 works fine.
