<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Defer closing replay files

close()ing replay files after storing a message can block on i/o under

certain conditions. Stuff the fds of the opened files into a list and

process that list only when a poll_wait() times out, which means there

are no messages waiting to be processed. Under flood conditions where

the list is full of open fds, they'll be reused when storing new

messages.
