epoll*: favor shutdown(2) for keepalive timeout

Triggering Errno::EBADF is tricky in multithreaded situations
due to possible race conditions and yet-to-be discovered bugs.
shutdown(2) is also safe against apps the fork() internally but
do not execve(2) nor set FD_CLOEXEC.

n.b. calling fork() after pthreads are spawned may not be safe
on all platforms w.r.t. malloc, but /is/ the case for glibc on
GNU/Linux.
