D compilation speed vs. go

Thank you for your timings.
When LDC has to compile many files (for example with xfbuild) can the LLVM back-end be kept running, to avoid some of those statup delays? (If this is not easy to do now, Chris Lattner can probably be willing to improve LLVM to help LDC devs, he is gentle when you ask him doable improvements).
