Calling wp_list_pages twice with different args does not work

[anonymousbugger]

The get_pages() function caches the page list and returns it in later calls.

For example
1: get_pages("child_of=3");
2: get_pages("child_of=24");

In this case the second call returns the same result as the first one.

This seems to have to do with the new page caching code, which as far as I can tell is so utterly broken that wp_list_pages() does not work at all for me. I've so far been unable to sufficiently patch it to restore the previous behavior and have since downgraded my site to 2005-02-14, until I have some more time to work on it. More info later...

Acknowledged.
Before these changes, it was broken in a different way: made one query per page, all the time.
I plan to fix this by having a function much like get_page_uri, but that can take multiple page IDs at the same time; or have get_page_uri accept an array of page IDs.
