I built the world with '-j', so it was hitting to the system pretty hard. I had 'sysstat' running while it was building everything and at one point the free memory was in the tens of megabytes. Simply doing a make world on the 8-core machine was enough to stall it (although I guess on the 8-core, the '-j' option would run more jobs.)
