At the risk of being considered dogmatic, this is (or should be) the #1
principle.  Whatever your bottleneck, figure out how you can turn it from
being a gatekeeper process into something you can parallelise (e.g. by
pairing, by publishing the pull request earlier, by involving QA or Systems
or PCI experts or whoever at the outset instead of the end)

For example, one thing that's been really useful for us is to use ephemeral
VMs (in Amazon or sometimes in Vagrant) to quickly deploy branches into
places where QA can poke at them on their own schedule, as development
continues on the developers' schedule. This makes QA signoff an async
process that needs no locking, but without the danger of "it works on my
machine"-type issues that may arise if they're testing on developer boxes.
