Guitarix is a host aimed to live performance. For performance reasons we
wont load a plugin on preset switch. So, all plugs which may be used
during a session been loaded already and been keep in memory. Other
plugs, which are not announced cant be used without explicitly load them
into the rack.

Still, we don't use RTLD_NODELETE (and can't see a benefit on using it)

Wasn't that more related to the underlying libs used by plugin GUI's
from the time were using shared toolkit lib's was supported (and
pronounced) by the LV2 specs? So that the host don't unload for example
the gtk lib's when a plugin which use it was unloaded, but a other one,
which may use it as well, still is loaded?
