That is deliberate.  The way it works, for now, is each of those
threads are blocking in VT_WAITACTIVE.  Last I checked, the signals
from VT_GETSTATE are only delivered to one process, in most cases:
Xorg.  And signals are yuck anyway.

So, looking forward, two possible paths are: fix the VT subsystem,
don't use the VT subsystem.  Maybe the later is a more viable option
these days...
