@fyrestone Please feel free to reopen the PR. I will also send a slack message. The issue here was that our Windows build failed due to this change. Please create a new PR that addresses that issue!

The error was previously

bazel-out/x64_windows-opt/bin/_virtual_includes/raylet_lib\ray/raylet/agent_manager.h(51): error C3646: 'agent_pid_': unknown override specifier

Sorry for the break. I will fix this problem. I should include the process.h in agent_manager.h, there is a typedef int pid_t; in process.h.

I noticed that the windows-msvc windows-msvc is always RED, why you guys merged these PRs to master?

[rkooo567]

.Window-msvc is always red because of test failures, but your original PR broke the build itself (so it couldn’t even start)

[robertnishihara]

@fyrestone @rkooo567 the "always red" state is a big problem (which is why PRs like this get merged accidentally). I'll try to fix that this weekend.
