Well, Vim doesn't use this threading stuff directly, the Gnome library
does, right?  So this initialization should be done in the Gnome
library.  It should be transparent to Vim.

I really dislike adding things to the main() function for some optional
library.  Each library should take care of its own initializations.
Otherwise we get a long list of things that have nothing to do with Vim.

But if the Gnome library refuses to do this, then we'll probably have to
do it in Vim anyway...
