Crash into the team boundary, this is basically a violent exit from
a visit and results in a DeadTeamException being thrown in the
previous team context.
Exception thrown when a {@linkplain Team#switchTo visit} or {@linkplain
Team#pushReservation reservation} cannot be secured because one of
the teams involved is dead.
The enable function is called just before the team is finished being
initialized, so you have a chance to do something, like start the GC
and finalizer threads.
