Local fix

Problem summary


    

  • System crashes on an abend due to trying to acquire the same
simple lock twice

    



Problem conclusion


    

  • Use SOCKET_LOCK2() instead of two calls to SOCKET_LOCK() when
acquiring two socket locks in a row. Also, to prevent deadlock
in uipc_slowtimo(), acquire the socket lock with a "try-lock".
