  There are two connection-oriented (TCP) CLinks: Pathways (connected sockets)
and Portals (listening sockets).

CLinks may be Synchronous or Asynchronous (more later).

To `service' a CLink means:
  Pathway: if data are available, then requests are read from the pathway and
	entered into the request queue (except private requests, which are
	handled immediately and discarded).
  Portal: if connections are pending, they are accepted and made into active
	CLinks (default synchronous) and a `new-connect' request is added to
	the local request queue.

------------------------------------------------------

Nice solution to deadlocking problem:

  Make flowcontrol a service of the UPPER layer (M layer), NOT the lower
	layer (AL layer)


--------------------------------------------------------------


Are these things necessary:

ALCheckRequestQueue


-----------------------------------------------------------------------

MProcessRequests()

  - calls ALServiceCLinks() with a NoWait option.
  - calls ALDequeueRequest(); if successful, processes that request.
