Subject: epoll/*: remove user-space array as active queue

This prevents pathological starvation cases where the user-space
ready-list can be repopulated infinitely.  With EPOLLONESHOT,
epoll itself may be used for this task (at a slightly higher
cost) by enabling read/write checks, as the epoll ready-list
preserves event ordering when used with EPOLLONESHOT.
