 I've found that it only crashes when deleting a screen that has a getty 
 running on it.  Deleting a screen that has no running programmes works.
 What is causing the problem is cv_destroy(&tp->t_rawcv) I believe that  getty 
 is waiting on that conditional variable as the crash says that the cv is in 
 Destroying the other cvs' as found in tty_free works.
 I would like to kill the getty before destroying the cvs' but I have no idea 
 how I've tried sending signals with no success, and I have no idea as to how 
 to make it wait until the process is killed, but I think this is the source 
 of the problem.
 Any ideas?
