Subject: [PATCH] chromium: create wakeup pipe with O_CLOEXEC
Since the sandbox thread is terminated by closing the pipe, forked
processes could keep the pipe alive for a longer time than intended,
and freeze RenderSandboxHostLinux::~RenderSandboxHostLinux().
This is all Linux-specific code, so use the glibc-specific pipe2()
function.
