I didn't expect magnum would commit this patch after I had called it in
here a "failed experiment".  Now that it's in there, we should either
revert it or fix it for non-OpenMP and benchmark on more systems.

I see you're reporting issues with non-OpenMP builds here:

but it makes no sense to try matching any non-OpenMP build issue to any
other patch until the obvious bugs in the "multi-threaded hash table
initialization" commit are fixed (or it is reverted).

FWIW, in an OpenMP-enabled build it works fine for me. ;-)  Just
provides arguably too little speedup to be worth it (and might actually
hurt performance on CPUs with turbo, etc.)
