If I remember correctly, the parent process (Python) and the child process (file) can be blocked if the child is blocked in a blocking write into a pipe (ex: stderr), whereas the pipe buffer is full (the size of the buffer is usually 4096 bytes) and the parent is reading all content of another pipe (ex: stdout). So it occurs if the process uses more than 1 pipe for standard input/output streams. In the case of platform, it looks like the issue cannot occur. I always prefer communicate() because I consider it safer :-) > Though it might be worth passing DEVNULL to stdin instead of inheriting, just > to be tidy. Yeah, maybe.
