Yup.

I'm not sure what to do about it, though.  One easy way to "fix this"
would be to not use replace-region-contents in json-pretty-print if the
region is very large...  but that's kinda just wallpapering over the
problem.

replace-region-contents itself could decide to not do all its fancy
stuff if the region is very large, and just replace the contents in the
normal way instead?
