Memory leak using BLOBs

Reported by smartmo...@gmail.com, Jun 12 2017

Issue description

UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36

Steps to reproduce the problem:
1. Go to websites that have a download system like mega.nz
2. Download any file
3. Have a look a the task manager before and after downloads

What is the expected behavior?
At the end of the downloads Chromium/Chrome should free memory usage related to that tab.

What went wrong?
Chromium/Chrome doens't free memory after downloads are finished. Blob-internals are all still there.

Did this work before? No 

Chrome version: 58.0.3029.110  Channel: n/a
OS Version: 
Flash Version:

Do you have devtools open? That causes memory to be held.

Otherwise, might be a dupe of issue 712684
Yes, if DevTools is open this issue occurs. Otherwise Chrome frees memory in few seconds. Thank you.

Components: Platform>DevTools
This issue comes up frequently enough we may want to try to mitigate the behavior change when DevTools is open, or display a warning of some sort. I don't know what's possible/easy here.
