bug#31138: Native json slower than json.el

[yyoncho]

HI Eli,

I will try with run-hooks = nil. (I still cannot reproduce the issue consistently). As a side note, I think that similar issue affects emacs dynamic modules based on my limited testing. Please reply back if you need a callstack. 

Thanks,

Ivan

OK, thanks.  I think I see the reason.

Does it work for you to bind run-hooks to nil around calls to
json-parse-string?
