Posting to multiple pages concurrently?

[GT]

Hey.
My app performs posts on user's behalf on a regular basis
The app posts to both profiles and pages

often when posting to pages, the 2nd and so on posts to a users page
get rejected by Facebook for:

Facebook error 400: OAuthException: (#100) The status you are trying
to publish is a duplicate of, or too similar to, one that we recently
posted to Twitter

Or similar errors

so basically my routine loops through all the Facebook pages a user
has authorised my app to work with and attempts to post the same
message to each of these pages, sequentially..

Im wondering if mini_fb can simply post to all of a given user's pages
at the same time, potentially avoiding these multi post errors.. or at
least improving performance?

so instead of using thsi:

success = fb.post(pageid, :type => :feed, :params => {:message =>
message})

i could try

success = fb.post(array_of_ids, :type => :feed, :params => {:message
=> message})

Anyone have any thoughts on this?
Thanks!
