This patch worked in our environment too - thanks Jakob.  The
"io_loop_handle_add: epoll_ctl" errors went away and the IMAP proxy works
as expected now.

I don't fully understand what this patch does to the epoll data structures
though... Can somebody confirm that this change is safe and its not going
to create any leaks or other weirdness?
