Interrupted connection should return control to the user since they may want to handle the signal that caused the interrupt. Otherwise, we might never give back control to the user (the timeout would error out but that causes a big delay).
socat.yml: in test 475, the test would send a SIGTERM after 3 seconds. We would continue to ignore this signal and continue to call `recvfrom`. Instead we should error out and give control back to the user.
Something broke in the actions/download-artifact action and it is not preserving symbolic links. It didn't get a new release so my guess is that something was updated in the node environment or in npm. This is a future proof solution to preserve the fs structure between upload and download.
work around hang from test 373 to 374
add setting SHELL env for socat test
remove some tests for exec sniffing and sorted address options failing with actions but not locally
