I have two complaints about sockets:

1, bidirectional sockets probably should've been ≥2 fd's, not 1.

2, non-blocking semantics and poll/select suck.

Can't blame anyone in 1983 for not getting "async I/O" right since we're still struggling; at least now we have some decent answers (like io_uring on Linux.)
