Under what circumstances?

It is possible, but not to likely, as the dirs are part of a package unpacked. 
User would have permissions. If portage is not being run as root. If run as 
root, only extended file attributions ( immutable ) can prevent root from 
removing. Not likely set in a packaged unpacked.

This part of the eclass is handling sources from VC. I am not sure how they 
can be pulled in with permissions that would prevent what ever user portage is 
running under from removing a directory.

Seems like it is not possible to generate the above permission issue.
