pre2 and pre4 with rails3 do count for total even if given :total_entries

[inspire22]

Loading development environment (Rails 3.0.9)
is=Item.paginate :page => 1, :per_page => 10, :total_entries => 100

Item Load (33.6ms) SELECT items.* FROM items LIMIT 10 OFFSET 0
SQL (11378.1ms) SELECT COUNT(*) FROM items

This is especially a problem with innodb, as count(*) is very slow.

Problem appears to be in active_record.rb the total_entries method does @total_entries ||=. But it's not set via the paginate call somehow.

I can't quire wrap my head around which is the Collection object's instance variables and which are in the active-record relation, so I can't quite follow how it should work.

Aah, perhaps it's because in the paginate submodule you set total_entries = wp_parse rather than self.total_entries = wp_parse? Or @total_entries. Hmm, hacking it and using @total_entries instead still doesn't show up with total_entries() is called.

I will look into this. I thought I supported this feature, but might be that I made a mistake. Thanks for reporting

For what it's worth, I'm seeing this in pre4 but not pre2.
