Bug#695182: [RFC] Reproducible OOM with just a few sleeps

[paul.szabo@sydney.edu.au]

Dear Pavel and Dave,

Yes, PAE is broken. Still, maybe the above needs slight correction:
non-PAE HIGHMEM4G passed the "sleep test": no OOM, nothing unexpected;
whereas PAE OOMed then hung (tested with various RAM from 3GB to 64GB).

The feeling I get is that amd64 is proposed as a drop-in replacement for
PAE, that support and development of PAE is gone, that PAE is dead.

Cheers, Paul
