Comment (by azaozz):

 Generally wpautop should be leaving the content of the `<pre>` tags
 untouched. How about we replace any `<pre> ... </pre>` with placeholders
 at the beginning and put them back at the end? That would not only remove
 this preg_replace_callback() (and the backtracking) but also speed up
 wpautop as it wouldn't backtrack through these parts of the post_content.

 Coding this wouldn't be hard: `preg_split('|</?pre[ >]|', $pee, -1,
 PREG_SPLIT_DELIM_CAPTURE)`, then go through the array and replace strings
 starting with `<pre` with incremental placeholder, keeping them for later
 in an `array('placeholder_#' => 'string', ...)`.
