Comment (by lunabyte):

 Tracked it down to the following:

 When a new blog is created, it's adding the following to the bottom of the
 htaccess file.

 {{{
 # BEGIN WordPress
 <IfModule mod_rewrite.c>
 RewriteEngine On
 RewriteBase /test2/
 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteCond %{REQUEST_FILENAME} !-d
 RewriteRule . /test2/index.php [L]
 </IfModule>

 # END WordPress
 }}}

 Note, that's below the normal htaccess file.

 Add another blog and the above is changed to reflect that new blog, so
 there is only one such additional entry into the htaccess file. However,
 regardless of what it is, it causes any blog to redirect infinitely.

 Still tracking where this is being inserted from, but it looks to be
 either from wp-admin/includes/misc.php or wp-included/rewrite.php.

 As a note, if the htaccess file isn't writable by the server (whatever
 user it is running as), then the htaccess file isn't touched and the error
 is not reproduced.
