Currently not at all. I'm thinking maybe some channel/tunnel effect would be needed to share open resources among threads. |

@tokiwa-software/developers looking for feedback on this.
Motivation: Currently there is no way to return a String backed by mapped_buffer without copying the buffer, (unless we are still inside the callback of the instated mmap-effect).
This PR adds a resource arena of some sorts that handles the closing of the open resources. This means file.open/use now returns a file, no callback anymore. This file can then be used whenever as long as inside of the resources arena.
The user still does not have to, and currently can not, manually close the file. It is manged by the resources effect. Also the user still does not need to handle
File_Descriptorin any way.
