Steps to reproduce the problem:
1. Take a computer with small amount of free memory;
2. Open a new window, add tens of tabs. Make sure the computer has started to use swap (is slowing down);
3. Close the window. Wait for freeing memory;
4. Restore the window from "Recently closed" menu or by pressing Cmd-Shift-T (Ctrl-Shift-T on Win/Linux).

What is the expected behavior?
The closed window is restoring. Tabs are being loaded gradually, one by one.

What went wrong?
The closed window is restoring. All tabs are being loaded immediately, concurrently, at the same moment - That hurts OS/computer. It slows down (or even freezes for some time) momentally, unexpectedly.

Did this work before? No 

Chrome version:   Channel: n/a
OS Version: OS X 10.12.3
Flash Version: 

I use "Continue where you left" option from the Settings. And when I start/restart Chrome all restored tabs are being loaded gradually. That's great.

But restoring recently closed tabs doesn't imply the same behaviour. It looks weird... as an incompleteness.

I have a patch.
(will add a CL soon).
