I'm thinking that maybe there is a way for two threads to share one stdout, which should resolve this, but I can't make it work, since U can't pickle file like object(stdout) to pass it to other thread. > Confusion abounds... You don't have to "pickle file like object..." for it to be used by a Python THREAD... But your mention of pipes makes me think you are using subprocesses and/or multiprocessing modules. Threads run in a shared environment (you may need to put a lock around the file object so that only one thread at a time does the I/O on that object), but processes are independent memory spaces. However, you may also encounter OS specific behavior WRT stdout/stderr when they are connected to a console. The OS itself may block/buffer output when there is a pending input on the same console. -- Wulfraed Dennis Lee Bieber AF6VN wlfraed@ix.netcom.com HTTP://wlfraed.home.netcom.com/
