Hi Vincenzo,
Is this the version with the trackpriority untouched?
We should not really change physics performance (even in that minor way) in tracking in 74X.

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_4_X IBs unless changes (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @Degano, @smuzaffar
