Three.js memory leak

I have noticed strange memory leak in three.js (r73). Steps to reproduce:

1)Open following link in Google Chrome ( 46.0.2490.80 m)

  1. Open DevTools -> Profiles – > Take Heap Snapshot. See my screenshot below:


  1. Take another heap snapshot after 10 seconds. As you can see the size of heap increased.


But if open this page locally on the computer without any server than heap size will be within the bounds of 4-6 Mb.


Why used memory size permanently increased in example and constant in case of locally page opening?

Thanks in advance!

Best regards, Vasily.
