Edward Tomasz Napierala d5aef6d6ca Pick 57553c3b1a5592dc4c03f3c6831d9b794e523865 from upstream:
Avoid touching all pages in extent_recycle for debug build.

    We may have a large number of pages with *zero set (since they are populated on
    demand).  Only check the first page to avoid paging in all of them.

This makes it easy to compare performance with and without 'retain:true'.
