io_timeouted - return a file descriptor over deadline

       io_timeouted  returns  the  next  file descriptor that is past it's deadline.  If no descriptors are past
       their deadlines, it returns -1.

       After io_timeouted() returned -1, you should wait  a  second  before  calling  it  again.   Checking  for
       connections  past  their deadline involves walking through the whole data structure, which may thrash the
       CPU cache needlessly.  Treat it as an expensive operation.
