Can you please sign (before more conflict emerges) ?
Thanks

@slava77 @StoyanStoynev if you are ok, I'll bypass the rest of the signatures, are you looking into this?

[StoyanStoynev]

I am not looking into this PR as Slava was checking it (intensively), he should say.

[slava77]

I will take a look later today.

for #4973 0e4ff6d
tested with extended tests in CMSSW_7_2_X_2014-08-18-1400 (test area sign410)
the results are the same as in the previous cid, as expected.

[ktf]

Bypassing other signatures since they were either already signed or L2s is MIA. Complain if not ok.
