So the gatekeeper would try to pull from the developers repos into the 
integration workspace and if a merge is required push back on the 
developer to resolve the conflicts. But wouldn't this then cause a slow 
down in getting the changes into the main repository? Meaning that 
instead of the developer getting immediate feedback from pushing 
directly to the main repository he would get feedback only when the 
gatekeeper processes the next batch of changes.
