Calling query.py from another directory does not work

[jmnybl]

ImportError: setlib/pytset.so: cannot open shared object file: No such file or directory

Bypassing currently by setting working directory to the code path. This assures that the code gets autogenerated to the right place and can also be correctly imported. The disadvantage is that two parallel runs will step on each others' toes and that write access to dep_search is required. Pending a better solution.
