core.runtime: loadLibrary and unloadLibrary?

[Rob T]

http://dlang.org/phobos/core_runtime.html#.Runtime.loadLibrary
I want to load shared libraries during runtime as plug-in's, but 
the consensus seemed to indicate that DMD is not yet ready for 
this. I wonder if these functions provide any useful plug-in 
support or not?

Thanks!
