Greeting-

It looks like something in head is giving swapping a problem.  I am
swapping on a file /usr/swap/0 since the system runs out of memory
trying to build the kernel.

This happened trying to rebuild the kernel.

swap_pager: indefinite wait buffer: bufobj: 0, blkno: 17323, size: 4096
swap_pager: indefinite wait buffer: bufobj: 0, blkno: 19458, size: 8192

swap_pager: indefinite wait buffer: bufobj: 0, blkno: 23547, size: 4096
swap_pager: indefinite wait buffer: bufobj: 0, blkno: 23547, size: 4096
swap_pager: indefinite wait buffer: bufobj: 0, blkno: 23547, size: 4096

The system is non-responsive and I guess I will have to drop to the
debugger and reset.
