I'm most interested in feedback on the design of polling.py and scheduling.py, and to a lesser extent on the design of sockets.py; main.py is just an example of how this style works out in practice.
What happens if two tasks try to do a read op (or two tasks try to do a write op) on the same file descriptor? It looks like the second one to do scheduling.block_r(fd) will cause the first task to be forgotten, causing the first task to block forever. Shouldn't there be a list of pending readers and a list of pending writers for each fd? -- Richard
