Excellent! This has greatly helped with KDE.

Quick question though. Where dependency_libs is large and references
other .la objects, would it be worthwhile to cache already-dlopen'ed
libraries? If so, what would happen if one of the dlopen'ed libraries
got updated while the program was running? Because we cached the fact
that the library was already loaded, the library would not be reloaded
(though I suppose we could use a stat cache on the modification time
of the file if necessary).
