We've got this test failure here on the Debian package. It appears randomly (however, oftenly), so it's hard to tell what triggers this, nor how to successfully reproduce it.

Anyway, any hint on this or a fix would be very welcome.

Comienza con testing/test_gateway.py::TestPopenGateway::test_waitclose_on_remote_killed y reproduce el fallo repetidamente, usando como contexto el informe de Debian enlazado y los registros de compilación. Se considera terminado cuando el caso de un proceso remoto terminado forzosamente se comporta de forma consistente, provocando EOFError desde waitclose e IOError desde channel.send, sin un segmentation fault.
