OK, I write to the pipe in the main thread, and I created a new thread for reading from the pipe, then it will print what it received from the pipe(). But, it seems it block at the "self.testfd.read()". So, is there and suggestion and explaination about it? Thanks in advance. -- http://mail.python.org/mailman/listinfo/python-list
