Forgot to reply to this comment:

We (ROOT project at CERN) create a shared library which hosts the 
symbols for LLVM,Clang and cling (our C++ interpreter). When we 
bootstrap we want to load the shared library. We cannot rely on 
getPermanentLibrary because the symbol is not yet available. Instead we 
want to open the handle externally and register it *after* its 
initialization. This patch allows the JIT and other services to continue 
to work for such setups.

Does that make sense?
