Can you give an example of that?

Rebuilds don't cause a different solution in the graph afaik; so, I
wouldn't see how that would form a big problem. I also think this would
still be covered by preserved-rebuild and/or revdep-rebuild afterwards.

In any case, I've not been experiencing problems with this; but am
interesting to know how this could go wrong, as no backtracking works
for me and I hope it will continue to do so.

Btw, this also makes me question how proper pkgcore can do rebuilds.

For that, _all_ caching would need to be removed before the first run;
when there is a mention of "the same", I doubt this was done at all.
