Wait for thumbnail creation before uncompressing next page

[workhorsy]

When it uncompress a page, it then creates a thumbnail. It does not wait for the thumbnail to be created before it starts uncompressing the next page. This often leads to all the thumbnails getting queued in memory. Then they are finally created after all the pages are uncompressed. This can lead to huge memory spikes, and makes it look like everything is loaded, when it is not.
