If you ask to be delisted it will show up right away in Spamhaus.org, but can take a while to be updated with whomever you are trying to send to.
I was recently listed (as part of a netblock) which effectively blocked me from ALL Google IPs (yikes!) and requested to be delisted. For Google to allow emails again, it only took a few hours after delisting, but I had read it can take up to 2 days for it to be updated in wherever is blocking you.
