DSOs can be easily loaded. Main difference from FFI module is that
DSO will not have any FFI arguments translations, because they are
already translated by means of DEFUN. Another difference is that DSO
will need to do job to exporting/kill its symbols, functions, etc
to/from elisp for itself (currently `load-module' does that job). But
it is easily achieved using _init()/_fini() functions controled by
dlopen()/dlclose(). However i'm not awared about situation for M$,
but who cares about M$? :)
Also, to be fully compatible it is possible to create special
`ffi-load-module-dso' function, which will do most of the job what
`load-module' do.
