tcsh doesn't bother doing any locking when merging .history, so if you
kill multiple sessions at once, it's very common to see entries get
lost, interlaced or doubled e.g:
#+1220363109
./setup.py uninsta#+1220237817
...
#+1220363109
./setup.py uninsta#+1220237817
#+1220363109
./setup.py uninstall -vv --manifest files.txt
#+1220363109
iles.txt
#+1220363109
d'
I see it a lot when I close Terminator and kill the 4+ terms in it at
the same time. If I ^D each term manually it's fine, if I kill half a
dozen at once I'll probably lose half the history entirely and the other
half will be badly mangled. I expect shutdown is having a similar
effect.
