This is why I've generally been opposed to trying to do too
many things with (:pagelist:) -- it can get slow.
This is especially true for trying to create things
such as dynamic trails, navigation menus, etc.

Have you tried setting $EnablePageListProtect = 0;
to see if that improves things?

Also, any time you can use a trail as a source of pages,
things go _much_ faster because PmWiki doesn't have to
search the wiki.d/ directory for candidate pages.  
So, instead of

> (:pagelist group=Team name=-RecentChanges fmt="#selectlistpages":)

use

  (:pagelist trail=Team.RecentChanges group=Team 
      name=-RecentChanges order=name fmt="#selectlistpages":)

Lastly, you might note that

> (:input form:)
> (:select+ team:)
> (:option :)Go Team
> (:pagelist group=Team name=-RecentChanges fmt="#selectlistpages":)
> (:selectend:)
> (:input end:)

produces invalid HTML, as this will have a <div> elements
embedded within a <select>...</select> element.
