Files silently fail to save when "emacs -nw <file>" is called from multiple terminals

[Andrew Pennebaker <andrew.pennebaker@gmail.com>]

I was planning to make the same code change to several projects, so I
opened a few Console 2 tabs and ran "emacs -nw README.md" in each of
them. I began making my changes to the REAMDE.md's in emacs and hit
C-x C-s to save. I would close emacs with C-x C-c and try to cat the
README.md's, but no such file was saved. No temporary files remained.
For each file, I had to start writing it all over again.

I suspect that somehow, multiple "emacs -nw" calls are interfering
with each other.

System:

$ specs emacs os
