How secure is this? One of the reasons for forking a process and then
killing it after a timeout in lambdabot/mueval is because a thread can
apparently block the GC from running with a tight enough loop and the
normal in-GHC method of killing threads doesn't work. Can one
simultaneously in a thread allocate ever more memory and suppress kill
signals?
