Comment 6 for bug 717944

The problem is memory usage and number of threads (aka cores).
Looking at the inital report it tries to load and remap 8 images at one time. This steps needs propably "too much" memory.
So we need to reduce memory usage or/and automatically restrict the number of threads depending on image sizes.

Workaround could be to limit the number of threads with command line option --ncores.
