Hello,

I don't think I've seen it reported before: running "make ptestlong" on 
Sage-6.6 after distclean crashed my server last night (Debian Wheezy with 
3.16 kernel, 2x Opteron 6272, 16 cores each, 128GB RAM, 64GB swap). Today 
the machine was unresponsive, on reboot logs have shown killing processes 
because of out of memory, starting with KVM. Rebooting it and trying to 
test things again:

...
sage -t --long --warn-long 92.2

This was the last untested file (normally tests finish in about 10 
minutes). Top process in top before killing:

Thank you,
