How can I move clearing assocoated views pages to cron run?

"Clear all cached views pages associated with a node on update" performs scan, that is slow. It often timeouts. On the other hand we have drush based cron call with virtually no timeout set.

I want to just save tne nid of an editef node, and maybe extra data required (tell me if there is any) and then perform the scan and clear to the drush cron call. Is there any simple way?

My approach would be to create module that would use nodeapi and save nid and operation in a table, and then feed it to an boost functions, specifically boost_nodeapi(). But boost nodeapi tests variables to see if the cleaning is on. And I want it to be off as I don't want it to happen on real node edits. Any way to circumvent that? I would rather avoid copying boost internals into my module. On the pther hand I don't see messing with variables on each cron run as a good idea.
