/* The default R behavior is achieved by using delayed=0. Setting delayed to 1 causes Rmainloop to return immediatelly. This is useful if you need to start the loop from a different event loop context, which can be achieved by using delayed start and sending a break to R at a later point. Since the top level context was created in Rmainloop, the next longjmp will in fact resume in the Rmainloop. At that point the delay flag is already cleared thus resuming the regular operation of R. All this is pretty much hacked, so you should fully understand what you're doing! */
