I am using mysql-5.0.21 version. This issue was discussed in the bugs 
list 4.x.x version and I believe the same has been closed(only for windows).
1. Connection is established to the server
2. sever goes down.
3. The read at the client hangs.

The timeout has been implemented for windows. Not for Linux?? If this is 
not required in Linux how do i handle the same in linux. Would I have to 
wait close to 15 min for the function to return? Can this be controlled 
through my.cnf or mysql_option. Why cant setsockopt to control the 
timeout be implemented on Linux too.

8938  12:10:11.040375 read(3, 0x8de33b0, 16384) = -1 EHOSTUNREACH (No 
route to host)
8938  12:25:36.521901 shutdown(3, 2 /* send and receive */) = -1 
ENOTCONN (Transport endpoint is not connected)

void vio_timeout(Vio *vio __attribute__((unused)),
         uint which __attribute__((unused)),
                 uint timeout __attribute__((unused)))
#ifdef __WIN__
  ulong wait_timeout= (ulong) timeout * 1000;
  (void) setsockopt(vio->sd, SOL_SOCKET,
    which ? SO_SNDTIMEO : SO_RCVTIMEO, (char*) &wait_timeout,
#endif /* __WIN__ */

Thanks and Regards
