Oops, the commit message of my 6da3e29fbb0745d1e9f023ecf6f86fa6f290385b did not intend to close this bug. It's just a preparation. The actual fix will come in the next push.

Also, it seems that my 6da3e29fbb0745d1e9f023ecf6f86fa6f290385b revealed some uncovered bug in unix_ipc.cc according to the test result.

//ipc:ipc_test                                                           FAILED in 25.1s

I'll file another bug to keep track of it.
