Could I trouble you or anyone else to help me implement this feature? I have some test processes, one that exits cleanly on sigterm and one that refuses and must be killed abruptly. In some experimentation on GHCi, things seem to go alright, but in test, either process reports that it has terminated with 15, which is incorrect.
Test code: https://github.com/MichaelXavier/Angel/blob/sigkill/test/Angel/JobSpec.hs#L38 Relevant implementation code: https://github.com/MichaelXavier/Angel/blob/sigkill/src/Angel/Job.hs#L161 https://github.com/MichaelXavier/Angel/blob/sigkill/src/Angel/Process.hs#L40 I've spent quite a bit of time trying different solutions to this and have failed to get the tests to pass.
