The previous implementations performed these + kinds of garbage collections without considering the + internal state of the process being garbage collected. In + order to be able to more easily and more efficiently + implement yielding native code, these types of garbage + collections have been rewritten. A garbage collection + like this is now triggered by an asynchronous request + signal, the actual garbage collection is performed by the + process being garbage collected itself, and finalized by + a reply signal to the process issuing the request. Using + this approach processes can disable garbage collection + and yield without having to set up the heap in a state + that can be garbage collected.</p> + <p> + The <seealso + marker="erts:erlang#garbage_collect/2"><c>garbage_collect/2</c></seealso>, + and <seealso + marker="erts:erlang#check_process_code/3"><c>check_process_code/3</c></seealso> + BIFs have been introduced.
