Now what's funny is that when I tried to compare how 32 threaded build 
would behave on a 8-core VM I couldn't do it because it OOMs with 
zsmalloc as zswap backend. With zblock it doesn't, though, and the 
results are:
real	12m14.012s
user	39m37.777s
sys	14m6.923s
Zswap:            440148 kB
Zswapped:         924452 kB
zswpin 594812
zswpout 2802454
zswpwb 10878
