net.server_epoll: Restore wantread flag after pause (fixes #1354) If a chunk of data has been received that is larger than the amount read at a time, then the connection is paused for a short time after which it tries to read some more. If, after that, there is still more data to read, it should do the same thing. However, because the "want read" flag is removed and was restored after the delayed reading, it would not schedule another delayed read.
