I found that enabling swapfile support in Kconfig also reduces the frequency
of OOMs on my sh7760.   While I don't experience your particular problem, my
personal observation is that since around >2.6.22 linux-sh may OOM without
actual swapspace a lot sooner  (i.e. post 2.6.25 I can't even do "emerge -pv
world" without the kernel OOMing on me! This is with unreviewed platform code,
so take this info with a mountain of salt).
