Well, unfortunately:

marcelo by (uid=0)

(2GB RAM, 4way, 4 setiathome's, 2 fillmem 1GB each)

I really think we need the "fail: loop again: try_to_free_pages()" logic,
Andrea: If there is not enough memory we HAVE to block in the page
reclaiming work.

I'll try do work on some logic like that in 1h or so...
