g_intern_static_string() and modules

[Federico Mena Quintero <federico ximian com>]

Hi,

Currently, we explicitly disallow the gtkfilesystemgnomevfs module from
being unloaded because some dumb part of libgnomeui assumes that it is
always in memory.  I don't remember the exact problem right now, but
finding it in the ChangeLog is left as an exercise for the reader.

My question in particular is about g_intern_static_string().  If I'm
a .so that is sometimes linked in, and sometimes dlopen()ed, how can I
know whether I should use g_intern_static_string() or g_intern_string()?
If I'm dlopen()ed, I can't intern a static string because it will cause
trouble when I'm dlclose()d.

The more general question, of course, is how to know when a library was
loaded at runtime so that this problem can be avoided.
