swap_pager: out of swap space during gnome_upgrade.sh

I have -CURRENT as of 03/14 running on a dell latitude d600.
This was un upgrade from 5.3-STABLE.
The laptop has 512Mb RAM and 1Gb of swap space.

root_at_yoda <~> 569# df -h

Today I'm trying to upgrade all glib/gtk/gnome libs following as per 20050312
(/usr/ports/UPDATING).

Reasonably early during the 4th and final stage of the gnome_upgrade.sh script (GNOME_UPGRADE_SH_VER=2.10-3
(during an openoffice-1.1 build)) /var/log/messages gets flooded with the following messages:

Mar 16 12:47:39 yoda kernel: pid 96533 (sort), uid 0, was killed: out of swap
space
Mar 16 12:47:40 yoda kernel: swap_pager: out of swap space
Mar 16 12:47:40 yoda kernel: swap_pager_getswapspace(16): failed

Mar 16 12:47:40 yoda kernel: pid 96611 (sort), uid 0, was killed: out of swap
space
Mar 16 12:47:41 yoda kernel: swap_pager: out of swap space
Mar 16 12:47:41 yoda kernel: swap_pager_getswapspace(16): failed

It always is referring to the sort(1) process.

I've not seen this behavior before during the 2 days running -CURRENT and
having upgraded several ports thru portupgrade(1).

Hopefully someone can point me in the right direction.
