Haiku crashes without KDL

[un_spacyar]

I had several crashes. It doesn't show a KDL. Just the Desktop freezes, with just me mouse pointer working. The Alt+Control+Del don't bring the process control, and usually just freezes the mouse pointer.

I'm using hrev53393 (x86_gcc2), on real hardware.

Usually, this crash appears under heavy load.

In the syslog, I get the following message:

This is an OOM, most likely caused by the same factors as #15264.
