     Type:  defect (bug)  |     Status:  new
 Priority:  normal        |  Milestone:  3.3
Component:  Multisite     |    Version:  3.0
 Severity:  critical      |   Keywords:
--------------------------+-----------------
 Steps to reproduce:

 1. Create a network.

 2. Create a second blog.

 3. Via BLOG_ID_CURRENT_SITE, set the second blog to be the main blog.

 4. Delete the original blog at the / path.

 wpmu_delete_blog() will wipe out all blogs LIKE blog\_prefix%, which nukes
 the entire network.

 Solution: iterate over and drop `$wpdb->tables('blog')` only.
