OK, Check_Selector is full of bugs (this is fixed in gcc CVS).  Also, stream
'Read and 'Write don't work well with non-blocking sockets: they try to
read (write) in a busy loop, consuming all CPU.  I didn't try most of the
other routines, perhaps they are perfect and I was unlucky to try the
only routines with problems.

PS:

(1) On line 367 of g-socket.adb, this

      Len := C.int'Max (Max (RSet) + 1, Len);

should be

      Len := C.int'Max (Max (WSet) + 1, Len);

(2) Check_Selector does not work for sockets with fd > 31.
Since normal files also take up fd's, you don't need to have
32 open sockets to see this.  This requires major changes to
fix, and is fixed in gcc CVS.
