Comment:

 I feel dirty after debugging this. Here's the flow:

 1) call {{{wpmu_delete_blog()}}}

 2) It calls {{{update_blog_status( $blog_id, 'deleted', 1 );}}}

 3) ...which calls {{{refresh_blog_details($blog_id);}}}

 4) Which does:

 {{{
 wp_cache_delete( $blog_id , 'blog-details' );
 wp_cache_delete( $blog_id . 'short' , 'blog-details' );
 wp_cache_delete( md5( $details->domain . $details->path )  , 'blog-lookup'
 );
 wp_cache_delete( 'current_blog_' . $details->domain, 'site-options' );
 wp_cache_delete( 'current_blog_' . $details->domain . $details->path,
 'site-options' );
 }}}

 5) ...but was missing:

 {{{
 wp_cache_delete( 'get_id_from_blogname_' . $details->blogname, 'blog-
 details' );
 }}}

 One line patch.
