The first attach involves signaling the target VM to start up the attach 
mechanism. So for the minimal VM or a VM running with attach disabled 
(or as Staffan pointed out, running with a different tmp directory) then 
the target VM gets a SIGQUIT and just prints the thread dump. It's hard 
to say what Piotr is running into but I think this at least explains it 
for the minimal VM.
