Comment (by matthijs):

 Maybe it's not for the revisions. Looking at the rules, it seems all the
 attachments are the problem. Each one has about 11 rules (22 lines), like:

 s:35:\"vacancies/474/attachment/([^/]+)/?$\";
 s:32:\"index.php?attachment=$matches[1]\";
 s:45:\"vacancies/474/attachment/([^/]+)/trackback/?$\";
 s:37:\"index.php?attachment=$matches[1]&tb=1\";
 s:65:\"vacancies/474/attachment/([^/]+)/feed/(feed|rdf|rss|rss2|atom)/?$\";
 s:49:\"index.php?attachment=$matches[1]&feed=$matches[2]\";
 s:60:\"vacancies/474/attachment/([^/]+)/(feed|rdf|rss|rss2|atom)/?$\";
 s:49:\"index.php?attachment=$matches[1]&feed=$matches[2]\";
 s:60:\"vacancies/474/attachment/([^/]+)/comment-page-([0-9]{1,})/?$\";
 s:50:\"index.php?attachment=$matches[1]&cpage=$matches[2]\";
 s:28:\"(vacancies/474)/trackback/?$\";
 s:37:\"index.php?attachment=$matches[1]&tb=1\";
 s:48:\"(vacancies/474)/feed/(feed|rdf|rss|rss2|atom)/?$\";
 s:49:\"index.php?attachment=$matches[1]&feed=$matches[2]\";
 s:43:\"(vacancies/474)/(feed|rdf|rss|rss2|atom)/?$\";
 s:49:\"index.php?attachment=$matches[1]&feed=$matches[2]\";
 s:36:\"(vacancies/474)/page/?([0-9]{1,})/?$\";
 s:50:\"index.php?attachment=$matches[1]&paged=$matches[2]\";
 s:43:\"(vacancies/474)/comment-page-([0-9]{1,})/?$\";
 s:50:\"index.php?attachment=$matches[1]&cpage=$matches[2]\";
 s:28:\"(vacancies/474)(/[0-9]+)?/?$\";
 s:49:\"index.php?attachment=$matches[1]&page=$matches[2]\";

 That page (vacancies) currently has only 2 attachments, but apparently
 wordpress remembers all previous attachments (which are still in the media
 gallery) and writes rules for all of them.

 So this is an expected behavior? Then does that mean that this will not
 scale to anything behind a few hundred pages or attachments?
