- Maintains a list of processes on each node (if select has been called on that node)
- Each process maybe has a semaphore on it (to use the semaphore code to maintain the process list)
> Could maybe use a mutex instead

+VFS_Select(int, fd_set* read, fd_set* write, fd_set* except)
+
+read is the set of sockets that we are waiting to read from
+write " " " be able to write to
+except " " " for possible errors on
+
+
+Hence, each VFS_Node has three listener lists (or just pointers)
+- One for when data is avaliable
+- One for when space is avaliable for writing
+- One for when an error occurs (closed pipe, etc ...)
