I would investigate in what cloudooo is doing, they already monitor the 
process and detect a runaway/memory-leaked process, or intervene when a 
conversion is spending more time than we would expect.

If we simply implement his logic in a small python tool and make it work 
on a directory of documents, we could run this command every night using 
the latest snapshot and record/log any debug output (in parallel if need 

And if we use the same (growing) set of documents we also test for 
regressions by having a directory of files that never failed, and a 
directory with files that have failed, and have the tool move the files 

And in the same time the robustness of the UNO python bindings is tests 

PS I would add cloudooo logic to unoconv, but I prefer to keep workarounds
    out of unoconv, as I prefer such errors to be reported rather than hide
    them from users.
