Expected behaviour

Tests should pass

Actual behaviour

    sends indefinite progress notifications:                FAIL
      Exception: Timed out waiting to receive a message from the server.
      Last message received:
      {
          "jsonrpc": "2.0",
          "method": "kick/done/hlint",
          "params": [
              "/home/owen/src/haskell-language-server/test/testdata/diagnostics/Foo.hs"
          ]
      }
      Use -p '/sends indefinite progress notifications/' to rerun this test only.

Debug information

Might have something to do with the linux/arm configuration I'm using? I've had this expose race conditions before, because different things just execute at different speeds on this machine...

Many of our tests are flaky, so it is unlikely to be a linux/arm specific issue.
