That's not entirely true; there's (experimental ?) work for dynld(2), and
the shipping compilers can already produce DLMs.  (That said, libdynld is
not yet part of the base system.)  dynld(2) provides a system reminiscent of
dlopen() and dlsym(), but no dynamic linkage is supported (only dynamic
loading).  It is quite tastefully done and is useful to have for some
applications (the python port springs to mind).
