Kernel: Add a mechanism for listening for changes to an inode.
The syscall is quite simple: int watch_file(const char* path, int path_length); It returns a file descriptor referring to a "InodeWatcher" object in the kernel. It becomes readable whenever something changes about the inode. Currently this is implemented by hooking the "metadata dirty bit" in Inode which isn't perfect, but it's a start. :^)
