Re: select+read on socket in guile,guile-gtk

[Steve Tell <tell@telltronics.org>]

Its probably bad form to follow up my own question, but I realized that
there might be another way to do what I'm trying to do...

if guile's cooperative threads play nice with guile-gtk -
Can I create and maniuplate Gtk+ GUIs from any thread?

thanks again,
Steve
