#3107 for background. I realized we don't have to wait for a V8 upgrade.

To prepare the ground for the use of MakeMirror in #3119, may I suggest to move this to a separate function ? setupDebugObjects() for example.

util: optimize promise introspection
9a1bc4e 
Use V8's builtin ObjectIsPromise() to check that the value is a promise
before creating the promise mirror.  Reduces garbage collector strain
in the (common) non-promise case, which is beneficial when inspecting
deep object graphs.

Thanks everyone, landed in dbe4844.

@targos I broke out the initialization into a separate function. It's kind of against my principles to make changes after a LGTM but well, just this time, because you asked.

Ben, can you please link the until commit as well?

The what now? You mean the original commit? That's bnoordhuis/node@bdfee10 but that's dead now.

EDIT: bnoordhuis/io.js@bdfee10 works though.
