System freeze when attempting to execute large binary not loaded to disk cache

[X512]

This is hrev53639 x86_64.

System has 8GB of RAM and page file is disabled.

When attempting to run blender directly after boot, executable loading stops at loading executable image and trying to open new windows or context menus cause permanent freeze of window thread. Systems become almost uncontrollable, normal shutdown process is not working.

strace:

~/Blender> strace -l blender -p 10 10 800 600

But after cat blender > /dev/null is executed blender runs normally.
