Hi, Is there a way to limit the usage of -resident- memory? Say I have 8GB RAM. What I would like is being able to say: no matter what, use up to 2GB resident memory, and as much virtual memory as you like. I have tried to play around with gdk_mem_maxsize and gkd_mmap_minsize, but with no luck so far. Maybe I haven't very clear yet how they work? Roberto
