Project Archives freezes with large includes

It looks like everything is copied/calculated in bulk and not incrementally

Try using fileset with / as the root and do a */.pdf or similar many hit pattern.

The Preview Table does not show it is actually working
When it returns there is a risk for outof memory since it is fetching all matching files instead of just a subset(preview)

When pressing finish the dialog just freezes waiting for the packaging to finish - why is that not done in a background job ?

During this i always end up getting an outofmemory exception ...
