This is the list of Accesses natively
 supported by the KittenOS NEO
 kernel. It does not include those
 that are handled by services,
 but does include the mechanism for
 creating & using services.

For the services, see us-perms.

Here, "*" means that everything after
 this point is considered an argument
 to the access.

"c.*": Component. Returns:
 list: Returns iterator over proxies.
       These proxies may be set up to
        be unalterable for obvious
        security reasons.
 For "filesystem", additionally:
  primary: The primaryDisk proxy.
  temporary: The RAM-FS proxy.
  (These entries are included in the
    above list - these fields serve
    to identify the components.)

"s.*": Allows receiving a signal.
       Totally useless for any signal
        prefixed with "k." or "x." -
        "k." is always let through,
        and "x." can't be sent to you
        in a situation where you
        don't have permission,
        under normal circumstances.

"k.root": The kernel's _ENV table.

"k.computer": The "computer" table,
               with wrapMeta applied,
               pullSignal removed,
               and also pushSignal.

"k.kill": function (pid) to kill any
           process on the system.

"r.*": Registers a service's API for
 retrieval via the "x." mechanism.
 Returns a:
 function (function (pkg, pid, send))
 While the registration is locked on
  success, attempting to use it will
  fail, as no handler has been given.
 The returned function finishes the
  registration with a callback used
  for when a process tries to use the
  registered API.
 What that API returns goes to the
  target process.
 The given "sendSig" function can be
  used to send an event to the target
  process, the type of which matches
  the "x." name of the access, and
  the parameters being those given to
  sendSig.
 So sendSig(1) from a service
  registered via "r.carrot" would
  generate the event: "x.carrot", 1.
 (NOTE: Regarding management of
  processes that die, just make sure
  to check for k.procdie events and
  handle as necessary.)

"x.*": Accesses a registered service
 API, returning whatever that service
 intends to give you. Also gives you
 "s.x.*" automatically to receive the
 output of sendSig.
