Findings are that gtk gets stuck in all threads waiting on poll-like 
functions. I wonder why do *we* want to wait infinitely. Or the other 
way: if there is a bug in glib, do we want to fix it or workaround it.

I will investigate, why the infinite wait is demanded by Emacs, but if 
you like to answer the above question in advance, that helps.

I use unstable Debian. When I change the infinite wait to something like 
0.1 sec, it seems to stop freezing. And undocumented function 
g_main_query_context returns sometimes 0 and -1. Maybe in this case our 
xgselect should not pass the infinite timeout to its further gnome calls.

Thanks,
