Thanks Stinner. Do you have some clues about this issue ? In my case, our test system use Popen to start a few infrastructure processes for tests going. After tests done we will kill all processes and start again for new round. Most of time it works fine. However we have some chances where one Popen hangs on "os.read(errpipe_read, 50000) forever. The close_fd is always true. I guess there is some subtle issue here.

Thanks Stinner.
