Enabling OCSB/CRL in Keychain Access slows down Mac App Store

Today I wandered why the Mac App Store on my Macbook Pro is much slower than it used to be, clicking on "Purchased" tab even froze the Mac App Store and I had to force quit of the App Store. Then I remembered that I turned on OCSB/CRL in Keychain Access because of the Comodo security breach. I turned off this feature and instantly the Mac App Store worked as fast as a few weeks ago.

My question: this security feature is very essential, even after the Comodo story. And I don't think that I am the only one who uses this feature, I read several articles about this after the Comodo incident. Will there be a fix for this problem? Will there be a Mac App Store that remains usable with OCSB/CRL enabled?
