I watched that about 7 years ago when it first came out, and at an hour long I'm not about to watch it again... From what I can recall those are things that rarely are important. There is a cost, but in most real world code they only add a few nanoseconds - I have more important things to worry about.
As a firmware developer commonly operating on devices with 32MHz of cpu, i am offended sir.
If your doing firmware you probably shouldn't be doing much memory allocation at runtime anyway to prevent memory fragmentation.
Even at 32Mhz you typically have more important things to worry about. These nanoseconds are unlikely to add up - the overhead from the underlying new/delete is going to be much worse.
