SSAS - Out of memory exception during processing

For a while now I been analysing a situation and i have got it down to a fine art now where by I do the following

1. Create a memory a memory intensive situation where i am using 85% of available memory and SSAS is working hard to free memory.
2. Process add a dimension and capture statistics.
3. Review statistics, contemplate the results and then tweak something.
4. Start at step 1 again.
