Submitted url for removal still shows pending status

[arin2u]

I submitted 63 urls for removal in webmaster tool. To block a page
from google bot, one of the following things should be done as per
google:

# Make sure the content is no longer live on the web. Requests for the
page or image you want to remove must return an HTTP 404 (not found)
or 410 status code.
# Block the content using a meta noindex tag.
# Block the content using a robots.txt file.

I made robots.txt and blocked by disallowing them. I submitted them 3
days back but still the status shows pending. When it will be removed?

Your help is urgently needed.

it took Google 15 days to remove my content
msn/live is still ignoring my robots file

in my case I am not too bothered but I understand how frustrating that can be
