  <p>This document was produced by a group operating under the <a href="http://www.w3.org/Consortium/Patent-Policy-20040205/">5
  February 2004 W3C Patent Policy</a>. W3C maintains a <a href="http://www.w3.org/2004/01/pp-impl/42538/status" rel="disclosure">public list of
  any patent disclosures</a> made in connection with the deliverables
  of the group; that page also includes instructions for disclosing a
  patent. An individual who has actual knowledge of a patent which the
  individual believes contains <a href="http://www.w3.org/Consortium/Patent-Policy-20040205/#def-essential">Essential
  Claim(s)</a> must disclose the information in accordance with <a href="http://www.w3.org/Consortium/Patent-Policy-20040205/#sec-Disclosure">section
  6 of the W3C Patent Policy</a>.

  <h2 class="no-num no-toc" id="issues">Issues</h2><p>The use of the storage mutex to avoid race conditions is
  currently considered by certain implementors to be too high a
  performance burden, to the point where allowing data corruption is
  considered preferable. Alternatives that do not require a
  user-agent-wide per-origin script lock are eagerly sought after. If
  reviewers have any suggestions, they are urged to send them to the
  addresses given in the previous section.<p>More details regarding this issue are available in these
