Just two question whether I understand this correctly: This patch aims to make
all (or just some and if so which) methods exposed through the Qt4 frontend by
Poppler::Document and Poppler::Page thread-safe, i.e. I could share my document
instance over several threads concurrently calling stuff like renderToImage and
search?

And I am supposed to check the POPPLER_QT4_THREADSAFE macro to find out whether
I need to lock document access? So for example:

#ifndef POPPLER_QT4_THREADSAFE
// locking goes here
#endif

// make Poppler do something

Best regards, Adam.

P.S.: The documentation comments have the "since 0.22" tag, is there a chance
this will make it into 0.22 even though 0.21 was already released?
