<p>
Class which can make any IO object rewindable, including non-rewindable
ones. It does this by buffering the data into a tempfile, which is
rewindable.
</p>
<p>
rack.input is required to be rewindable, so if your input stream IO is
non-rewindable by nature (e.g. a pipe or a socket) then you can wrap it in
an object of this class to easily make it rewindable.
</p>
<p>
Don‘t forget to call <a href="RewindableInput.html#M000450">close</a>
when you‘re done. This frees up temporary resources that <a
href="RewindableInput.html">RewindableInput</a> uses, though it does
<b>not</b> <a href="RewindableInput.html#M000450">close</a> the original IO
object.
