Public bug reported:

Hello,

When system starts using swap massively (~1GB of 8GB available), the system freezes a few time later and require to press the reset button.
It is happening when using rawtherapee (latest version from github).

I think rawtherapee may have a bug with memory usage, according to my
experience in 14.04 with RT gtk2 version (not stressing swap), but the
system should not freeze when using swap.

vm.swappiness = 0
8GB RAM
