proxy: ensure GC sees the client socket upon reactivation

Reactivating a client socket after the proxied response is
complete requires the object remain visible to the Ruby GC while
no thread is accessing it.  So we must place the object back
into the fdmap to prevent the GC from eating it (and having
epoll return an invalid pointer).
