Ok I'll narrow down my question:


To make Gambit work well (with --enable-single-host) on 4.2.* and
4.3.*, is "-fno-move-loop-invariants"
a complete solution?

(The prob AFAIK was that it'd skyrocket to 20-75GB RAM consumption -
and "-fno-move-loop-invariants"
would bring it down to 1-2GB instead?)
