It is to be expected that in order to improve the compiler's behavior,
the compiler runs more slowly.

The main worry is the speed impact on non-compilation tasks, mostly
because of the impact on EQ (where Alan's benchmark suggest a 1% impact,
tho it would be good to have other measurements to confirm that).
