>Description:
        UVM is unable to kill processes that reach out-of-swap condition
        and the system locks up. This is not related to UVM directly,
        because the correct behavior is exibithed on NetBSD/i386.
        
        Please see the following URL for a more precise description
        of the problem:
        http://mail-index.netbsd.org/port-sparc/2005/03/17/0002.html

>How-To-Repeat:
        Run several instances of this program or unlimit the data size
        (to achieve out-of-swap condition):
        
        int main(void)
        {
                for (; malloc(4); )
                        continue;
                return 0;
        }

>Fix:
        Unknown ATM.
