I think that what you are suggesting is to pass the accumulated "pulled 
package" list into _alpm_resolvedeps for each subsequent call to that 
function, so that each subsequent call can first look into the 
already-resolved list of packages from previous resolves.

This is a great addition to my proposal and it eliminates the 
performance concerns.

I will re-implement this way and re-submit my patches.

Thanks for your help and your advice.

Best wishes,
