I tried it on a i686 lap that only has 256 MB of RAM with a 600 MB mfs
mounted at /mfs.

I did it based on 2.99.10 sources from the 25th of October, kernel+userland.

The only messages I got were such:
/netbsd: UVM: pid 5443 (xearth), uid 1000 killed: out of swap
/netbsd: UVM: pid 9583 (mozilla-bin), uid 1000 killed: out of swap
/netbsd: UVM: pid 21325 (XFree86), uid 0 killed: out of swap

and some other messages from userland that said that no more memory
could be allocated what resulted in /mfs not getting further filled.

But it did not hang.
