Reclaim may reclaim the same page more than once
A operation during reclaim is not thread-safe, so under some conditions, it may be possible for one thread to remove a page from the reclaim pages list, while another thread puts the page back on the list. This would result in an attempt to reclaim the same page more than once. This may or may not trigger an error at the time; subsequently, page errors may occur.
Workaround
This bug is expected to be very rare, as in practice, other code prevents the bug from manifesting.
