If would seem to me to be more efficient to do OCSP verifications on the connections before, if they are long - during, the the SSL connection. Downloading and parsing the many thousands of revoked certificates seems to be an inefficient way of verifying the active connections (which is undoubtly less). Having said that if you really want to parse crls look at the openssl/apps/crl.c in the openssl source code.
