There is a known issue regarding devfs device node removal, which pts 
exercises extensively.  I'm not sure what the status of fixing this is 
currently (I know it has been looked at), but it would be very nice to see 
this fixed in the immediate future.  Right now, kern.pts.enable defaults to 0, 
but it would be nice to set it to 1 as the default for 7.0.  Since it affects 
application behavior, it would be better to do this sooner rather than later 
in order to give both base system apps and ports a chance to settle out.
