NAME
       io_timeouted - return a file descriptor over deadline

SYNTAX
       #include <io.h>

       int64 io_timeouted();

DESCRIPTION
       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.
