Oh, OK. I didn't know that. The only good news is that this behavior is 
not expected by the shadow3 algorithm, since most of the developing time 
has been spent in ways to prevent completely brute-force search of 
writable mappings. I'll get back with a patch to fix this after I can 
reproduce it on my machine.

Thanks,
Gianluca
