Yeah. Most IO operations do need a way to cancel. And hopefully all of
them will be returning Promises.
I definitely agree that providing cancelability on Promise will add
complexity. That said, the pattern of making heavy long-running APIs
return a Promise, and wanting to enable cancelling them, is likely
going to be common.
So finding a good solution to that pattern seems worthwhile.
