The attached script hangs while using 100% on Python 3.5.1 but not on Python 3.4.3. Tested both on Gentoo Linux and Ubuntu Linux. The loop seems to be in PyErr_SetObject in a loop that recursively go through PyException_GetContext. subprocess.Popen seems to cause the issue while calling io.open. strace reveals a error on call to lseek on a pipe. The issue does not happen when using nested "with" instead of ExitStack.

subprocess.Popen seems to cause the issue while calling io.open. strace reveals a error on call to lseek on a pipe.
