[New-bugs-announce] [issue5870] subprocess.DEVNULL

Jean Brouwers report at bugs.python.org

New submission from Jean Brouwers <MrJean1 at Gmail.com>:

The subprocess module exposes the PIPE and STDOUT constants to be used 
for the stdin, stdout or stderr keyword arguments.

Often, stderr needs to be redirected to /dev/null (on posix).  It would 
nice if another constant was available for that purpose, e.g. 
subprocess.DEVNULL.

Perhaps, that might be as simple as

DEVNULL = os.open(os.devnull, os.OS_RDWR)

and re-use the same, single file descriptor.
