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".
Temporary fix
