     This may be an Elm bug.  I seem to remember a patch to Elm 1.7 that fixed
a similar problem that occured if you exited Elm and then quickly logged out.
Basically, a SIGHUP signal was being sent to the process spawned by Elm, and
that signal was not being caught.  The fix was to change Elm to ignore the
signal (I think).
