why? Are you sure 'call' is not used multiple times? (first call to 'call' will
replace the process completely). Also windows branch now should looks like
sys.exit(subprocess2.call(....)) to match what linux branch does.

Also you don't pass 'env' in here.

I thought it would've been cleaner, but on second thought the extra code and
confusion isn't worth it.  Removed.
