Hi, I'm trying to create a nice api for slurping an io.Reader into memory (if size is under threshold), or into a temporary file that's Mmaped.
Everything works, if I give back an explicit io.Closer beside the []byte of the data, that Unmaps the []btye region when the caller has finished. I wanted to get rid of that io.Closer, and use runtime.SetFinalizer(&p,...) But that p is collected when not in use - even when a subslice is in use! I've tried to runtime.SetFinalizer(&p[0]), but that complains that that address is not an allocated - which is understandable, as that's allocated by the OS, not by the Go GC. So, how to Unmap only when all the references of the backing array gets garbage collected? Or any other idea?
