From: Arnaldo Carvalho de Melo <acme@redhat.com>
As the way DSOs are created are normally via dsos__findnew, so that we don't have to load the same dso multiple times for multiple maps (think about /lib64/libc.so.6), so they may be shared and dso__delete() should be left to be done as part of the map destruction process.
This will all be properly solved by reference counting struct dso, which will be done soon.
