As things stand there are multiple races in the CONFIG_SITE handling where checksums can change depending on whether site directories exist or not when parsing happens. This is bad. Secondly, there is a build race that occurs if you build virtuals in parallel with the "main" recipe, since the main recipe is parsed when the virtual is (since it sets variables like BBCLASSEXTEND) and with the current code, it may look for files and directories which could be created/destroyed which the loop is executing. This is also bad. The aclocal-copy directory should only ever be accessed by the call from autotools.bbclass. This changes the parameter name to make it clear and ensures all callers have the right usage, neatly avoiding all the problems above. Also added better comments.
