Hi,
I thought that due to high throughput of the linux-kernel mailing list
my email will not get a reply if it didn't happen in a day so I allowed
myself to write another email to linux-mm as well as it was suggested to
me on #debian-kernel.
The email is here:
Subject: Exhausting memory makes the system unresponsive but doesn't
invoke OOM killer

I have also updated the description in the repository:
https://github.com/wodny/crasher
Contrary to my original suspicion the OOM killer doesn't need much time
to clean up, it just isn't invoked. Johannes Weiner explained the
probable cause to me in a response in the linux-mm thread.
