1. There was a bug that was not handling correctly the
case for which the interrogator requests an accessibility
node info and the message describing how to fetch the
latter for the same process case was delivered after the
code that checks whether the message is there in order to
dispatch it is executed. Now the message handling is done
correctly - the caller checks if the message is present and
if so processes it, otherwise the caller sleeps and is
interrupted if such a message arrives.
