So far so good. Your patch seam to have fixed the "random" crash That I was
able to replicate when I was loading my 3 many tabs browsers and phpstorm in
the same time and I can use my IDE without crashing too.

Maybe I got really lucky too. But it's been more than a day without crash and
without the nodma "fix"
