Subject: [PATCH 1/2] test that terminate causes EOFError

try with sigterm

try with sigkill too

update tests

add loop test

add explicit EOF

another attempt

cleanup

try again

don't skip the test

skip control tests for now

use new event loop

reinstate control tests

fix handling of event loop

follow docs

try skipping the loop test

try conpty only

remove more winpty

see if removing the extra read works

try without extra write and no loop test

back to original code

try winpty only

timeout after 15 minutes

try with conpty only

remove eof handling

try without capture

run pytest directly

pin pytest

fix shell quoting

use 10 minute timeout
