[using a FS just for WRKDIRs]

Yes, without any doupt this is very fast.

Unfortunately it's not an option here. We have to keep the current  
semantic and take the usage scenarios into account, which are possible  
currently. What you propose is not usable as a plugin-replacement for  
the current "make clean" (and that's what we try to achieve).

Bye,
Alexander.
