Another interesting side effect is that *if* you install the headers, 
DKMS will work for your new kernel. That could both be what you want (e 
g to make virtualbox etc work) but also what you don't want (if you want 
a clean test).

Hmm, this seems dangerous to me, at least in combination with the "-j" 
switch. Isn't there a possibility that clean will run in parallel with 
the binary targets, or should this prevented inside the makefiles somehow?

Combining "binary-headers" with "binary-generic" seems safe to me though.
