try to read what's missing, you'll end with EAGAIN if there is no data
yet. In that case you either try a busy loop or you save number of
read bytes and what's missing and continue on next next fd_handler.

please, use strerror(errno) to make it easier to figure out what's happened.

this termination condition is weird, if it's "retry" it should mean we
should retry, not that it finished fine.
