Hi!

Is

[http://ruby-gnome2.sourceforge.jp/hiki.cgi?cmd=view&p=tips\_threads](http://ruby-gnome2.sourceforge.jp/hiki.cgi?cmd=view&p=tips_threads)

still relevant in Ruby 1.9?

If so, how does this work with GLib::MainLoop.new and implicit  
mainloops created with, for example, Gtk::Dialog.run?

AFAIK, yes. The problem is not ruby, but GTK, which is not thread-safe.  
See my question on the vala list :

I have no idea, it’s too bare metal for me.
