fastsim signature is missing here.
Are there any issues to sign?

+1

no issue, just a bit tired after signing for the 3rd time for 1 line of FastSim code :-)

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_1_X IBs unless changes (tests are also fine). @nclopezo, @ktf can you please take care of it?

[lgray]

@lveldere Next time I'll buy you a beer :-)

@lgray - a belated question on this pull request - while available in python versions used by CMSSW (2.7+), importlib is not available in python 2.6 which we appear to need to support at least for the moment ( :( ) . Is there something in import lib that does something more than import that you rely on in this PR?

@davidlange6 importlib is used so that I can (without too much hassle) dynamically grab cut flow configurations. I'd need to go figure out the old way to do this.

I think
d=import(blah) does the same thing. Is there an easy way for me to test? (e.g., if I can run the miniAOD in 7_0_9 plus this change, is that sufficient?)

Just make the appropriate change in https://github.com/cms-sw/cmssw/pull/5015/files#diff-e7553c3b18dedb4aa37ad8a4fa36b390R30 and then you can try running a miniAOD matrix test.

[davidlange6]

Done - I just make a PR (#5501)
