This was a supported configuration. It used to be possible to switch
between consoles using userconfig. When consoles use the same resources,
the first one that happens the be attached should allocate the resources
and the others should fail to attach when they can't allocate the
resources. Things might work better if pcattach() actually checked
for success of its resource allocations.
