Hm.  A very quick look at the patch concerns me a bit.  Am I right  
that, if you apply the patch, then requests that are currently  
raising a NotYet for you will instead silently fail, not cataloging  
what you requested?  That seems undesirable to me.  I'd prefer the  
exception.

If I'm on the right track here, then the extentcatalog in the  
zc.catalog package in the sandbox probably is one of possibly many  
other better solutions than the patch.  It postpones cataloging to  
the end of the transaction, which I believe will remove the NotYet  
exceptions *and* successfully catalog your data.

Apologies if my quick patch read is off base.
