[Nottingham] Limiting process physical memory - how?

[Roger Light]

Hi Martin,

I think cgroups should do what you want:

https://wiki.archlinux.org/index.php/Cgroups

Note the line "Note that the memory limit applies to RAM use only --
once tasks hit this limit, they will begin to swap. But it won't
affect the performance of other processes significantly."

Cheers,

Roger
