csh history and pts

Hi,

Since the MPSAFETTY landing and pts being the default csh seems to loose 
the contents of ~/.history when "shutdown -r now" is issued, I'm not 
sure about the timeframe but I have not noticed this before and I use 
history quite a bit.

Steps to reproduce (tested with root):
1) Login on console (ttyv0)
2) Issued a couple of commands
3) Logout
4) Login
5) 'history' and your previous session shows up, all good.
6) 'shutdown -r now'
7) After boot, login, 'history' and it's blank.

At step #6 a reboot(8) does not cause this, only shutdown(8), or at 
least so it seems. Does shutdown(8) send a evil signal to csh so it 
looses the history?

Relevant parts of .cshrc:
set history = 2000
set savehist = (2000 merge)
