Oops, my mind was stuck a little bit in the past when I wrote this. When I
wrote
libpds there weren't any support for several dsp graphs, which I guess
you are using to get multiple instances (?). In that case, it might work
to create a wrapper plugin (as I suggested), and load your actual plugin
once with RTLD_GLOBAL, but only if it hadn't already been loaded. I've been
meaning to do this for libpds for a very long time now, but it's been so
much other things to do.
