Never seen this. Why would fsync block typing unless vim was doing
disk IO for every keystroke?


Not for every keystroke, but after some time it calls fsync(). During execution of that call, keyboard is blocked. It is not normally problem (fsync executes very fastly), but it starts to be problem in case of extremely overloaded system.
