Maybe a good middle-ground solution would be to defer the reading of the 
history file until history is actually used?

E.g. in my examples there was no reading of input from the user, and 
there will be many read-life scenarios like that.

Perhaps commands like comint-previous-input could check whether the ring 
is not initialized yet and call comint-read-input-ring, rather than have 
this call performed eagerly at the end of shell-mode.
