    Relevant test case:
    https://github.com/dotnet/runtime/blob/50ba405797f6cc57d57ff4d2503079b4c32acc7b/src/libraries/System.Diagnostics.Process/tests/ProcessTests.cs#L2289C45-L2298

    Seems to me like that last process is the one, but it's name was truncated:
    System.Diagnostics.Process (123456789012345)
