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 dead‐
       line.  If no descriptors are past their deadlines, it returns -1.

       After io_timeouted() returned -1, you should wait a second before call‐
       ing  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.
