"uitest: add timeout for blocking actions", I assume.  Should we revert it?

For one, as Michael already responded, many builds (local, 
Gerrit/Jenkins, other tinderboxes) now fail 
UITest_writerperfect_epubexport with what looks like random "raise 
DialogNotClosedException()".  Gut feeling is that it's way more than 
used to fail UITest_writerperfect_epubexport with a deadlock.

For another, as I'd written in another mail in this thread, it's not 
clear to me what we gain with such a timeout, anyway.
