You should have pushed it to magnum-jumbo. Now I had to cherry-pick the
fixes "backwards" to magnum-jumbo and could not avoid it being merged
back as a dupe no-op commit to bleeding, confusing history. No problem,
just consider this for future patches.
Note that magnum-jumbo is just as unstable (or stable) as bleeding-jumbo
(at least in terms of Jumbo code). The only intended difference is they
are based on different core versions. Normally, the only thing that
should be directly committed to bleeding are fixes/workarounds/adaptions
for CVS core. Other than that, it's just a merge branch.
Anyway, it scales just fine on my gear on OpenSSL (1.0.1-4ubuntu5.3):
Benchmarking: WoW (Battlenet) SRP sha1 [32/64 oSSL-exp]... DONE
Raw: 24424 c/s real, 24424 c/s virtual
Benchmarking: WoW (Battlenet) SRP sha1 [32/64 oSSL-exp]... (2xOMP) DONE
Raw: 45623 c/s real, 22925 c/s virtual
...but a GMP build now fails self-test, OMP or not:
Benchmarking: WoW (Battlenet) SRP sha1 [32/64 GMP-exp]... FAILED
(get_hash[0](0))
Benchmarking: WoW (Battlenet) SRP sha1 [32/64 GMP-exp]... (2xOMP) FAILED
(get_hash[0](0))
Again, fixes to magnum-jumbo please!

I agree, that will be better in the long run. Though the file name can
stay IMO (I just don't think it matters, do as you wish).
