current shell's bash history lost on reboot

[Dusty Mabe]

The other day during the Atomic Test Day jzb and I noticed that we
were losing bash history (seemingly randomly). Today I dug into it a 
bit more. If you reboot a machine from a bash session then you will
lose all of your history for that session. Note the following is from
the F21 Cloud image: 

[root at f21 ~]# cat .bash_history | wc -l
2
[root at f21 ~]# history | wc -l
123
[root at f21 ~]# reboot

[fedora at f21 ~]$ sudo su -
[root at f21 ~]# history | wc -l
3

Has anyone else seen this? Is there an existing bug report? 

If you guys can confirm you are having this behavior then I will open
a report. Alos please see [1] [2] where suse was having a similar problem.
