So I've tested 1+2 for a few days - once I've rebooted for another reason,
but today happened this to me (with ~2day uptime)

For some reason my machine went ouf of memory and OOM killed
firefox and then even whole Xsession.

Unsure whether it's related to those 2 patches - but I've never had
such OOM failure before.

Should I experiment now with 1+3 - or is there newer thing to test ?
