128
The 2.0 behavior matches my shells and some searching: it's SIGKILL (9) + exited-due-to-signal (128).
This was discovered when we updated MSBuild to use the preview2 runtime for testing (worked around with dotnet/msbuild@a476aa5). The repro there is fairly complicated, since we don't use Process.Kill(), instead manually killing an entire process tree.
In MSBuild, we sent SIGTERM and expect 143 instead of 137, but I assume it's the same underlying cause.
Mono does not exhibit this behavior on macOS High Sierra, so I don't think it's an OS change.
