Why not just get the update list (complete) and:

1. if it can be depsolved, return the list
2. if not, then start processing each package and depsolving each one.

so we only use the "go slow" case when the repos are broken.

not "available" - that's for searching. you want low, high, normal,
security etc.

Sure, we just need to find a sane English version of "cannot depsolve" -
I appreciate this isn't an easy problem to fix.
