Frankly, I have had enough failures of parallel make that I think doing

open to persuasion.
Really? I routinely use -j4 for building, and it's been a long time
since I've seen failures. I can believe that for instance "make check"
in contrib would have a problem running in parallel, but the build
process per se seems reliable enough from here.
Both cases were vpath builds, which is what I usually use, if that's a
useful data point.
Maybe I run on lower level hardware than you do. I saw this again this
afternoon after I posted the above. In both cases this was the machine
that runs the buildfarm's crake. I'll try to get a handle on it.
