Shintaro Kawamura 427f1becb9 swap: suspend device processes using SIGSTOP signal ... ProcessesGuard stops all the crosvm processes except the caller process using SIGSTOP signal because we must guarantee that no one changes the guest memory contents while vmm-swap out. This is a short term solution and will be replaced with device suspension feature later.
