Is that correct? It was never my plan to introduce this restriction. I just want to get rid of the Deferreds in the preprocessing pool because I think that they are unnecessary there.<br></div></blockquote>Then by all means go ahead and speed up the preprocessing. :)</div><div><font class="Apple-style-span" face="Nuri" size="1"><span class="Apple-style-span" style="font-size: 9px;"><font class="Apple-style-span" face="Helvetica"><span class="Apple-style-span" style="font-size: medium;"><br></span></font></span></font></div><div apple-content-edited="true"><span class="Apple-style-span" style="border-collapse: separate;
