I reversed this (patch attached) and now my build with ulimit -v450000
passes. But the total virtual memory usage didn't drop that much. It was
around 454MB top usage, to 438MB top usage. Build time increased with
several minutes. Maybe this was just the tipping point for your setup?

Still looking for some other explanation why this seems to show up just
now.

Cheers,
