exact scenario was as follows:
- prog gets EPOLLOUT (write() won't block)
- prog writes()'s data to REDIS ("successfully")

After this I see that I need to reconnect, but I've already send
some data which had gone to nowhere.

but it is not the case.
errhh... usual blocking sockets, of course.
however then I have to deal with multiprocess/multithread
architechture, but my goal was fine-graned concurrency
within single process.
