Created attachment 67775

complete solution for testing

Here now my complete solution to make at least the okular usages of the qt
library thread safe.
1. I made the changes of comment 57.
2. I made a few changes to solve comment 55 (I found a PDF on my local harddisk
which had the same problem)
3. I made some additional changes to make the save of a document thread safe
(In this case I need to lock the doc->xref against any further changes until
the save is complete)
4. I implement the annotation stuff.
I made several tests, and didn't run into any problems, but I want to regtest
the changes at least with pdftoppm at the weekend. But perhaps You'll find also
some time to make some tests.
