I've reviewed the use of dpkg-query and, indeed, there were some bugs in the
code:
1.- the call to dpkg-query was run as a subprocess and the script did not
wait for the process to stop, so the file was found *not* to be
a part of a package
2.- the script was making dpkg-query calls for all the instances of a file
even if the file appeared more than once (i.e. a removed library that many
processes were using) which leads it to be *very* CPU intensive if you've
done a full upgrade which includes many core libraries (i.e.
used by many processes)
I have submitted a fix to our GIT repository [1]. Once we confirm that this
fix is OK and does not introduced any new bugs we will upload it.
