Golf 241 released

• This release improves memory handling, which is now faster. Also, several issues with process-scoped memory, such as leaking in some cases, has been resolved. 
• delete-string will now always delete ordinary (non process-scoped) memory if not referenced prior to deletion, otherwise memory is always released at the end of request. This strikes a good balance between the ability to delete memory while request is executing (if needed), and at the same time, have an automatic memory de-allocator and safety mechanism that's high-performance because it's very lightweight.
