rospack is too slow

edit

hi,

As mentioned here ( http://wiki.ros.org/rospack/Troublesh... ), rospack is slow. it seem that it takes a lot of time in share/common-lisp and share/maven, but they are just genereted files and not package, so is it make sense to add rospack_nosubdirs file under these directory?
