Bring fully asynchronous completion by polling for completions with a timer then calling completefunc once the completions are ready. Use the start column returned by the server in completefunc. Immediately display the last completion on the TextChangedI event to prevent the popup menu disappearing while waiting for the completions. Handle the TextChangedI event not being triggered while the completion menu is open by closing the menu when inserting a character through the InsertCharPre event, and when deleting a character on the <BS> and <C-h> keys.
