bug#851: Takes several minutes to load 512k C header

[Michael Meeks]

        I try to load the attached file (when un-compressed). It's 512k of
text, but I have a fast multi-GHz machine with GBs of spare RAM etc. and
I can load 20+Mb .txt files in emacs just fine normally.

        Loading this generates several minutes of non-responsiveness.

        HTH,

                Michael.
