The most difficult and unavoidable part about socket programming is
tasking. We need reader and writer tasks or else socket-select-driven
co-routines. The reader and writer parts have to communicate each other in
some intricate way because it is two tasks but one protocol state machine,
or one task and many state machines in the case of socket select. There is
the issue of blocking socket I/O non-abortable by Ada means. All this
incredibly complicates design.

If Ada ever have to support sockets it should be a high level Ada
tasking-friendly abstraction, which I am not ready to outline.
