has anyone found a solution to this one?

3.18-rc5 has kswapd0 hogging the CPU - haven't seen ksoftirqd0 yet.
Unpacking a large tarball tends to trigger this for me.

The only workaround I have is to drop caches regularily
(/proc/sys/vm/drop_caches) when MemFree is getting low.  All my OBS
build workers are stable running 3.11.6 with this workaround.
