When an epoll set includes accelerated sockets and is nested inside another epoll set, the following can occur with the outer set:

  • it might not always get notified about socket readiness
  • after a socket becomes ready, its state cannot be cleared.

This limitation is known to affect EF_UL_EPOLL=3.
