I can recreate this using the minimal VM, which doesn't support

have for the attach mechanism ??
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.
