If the shared library really is shared -- i.e., used by two or more
programs that you are actually running -- then you can treat it as if it

If you never run more than one program that uses it, then you should
count the library as part of that program.

Many of the shared libraries circulating in the open source world are
what I call vanity libraries. Their authors would like to think they're
getting more widespread use, but in truth no one uses them but
