GLib 2.2 (and possibly older versions) contains a bug which causes random
heap corruptions in multithreaded programs. It has been reported to the GLib
developers, and has been fixed in the GLib CVS. (GLib bug #127096) GLib 2.4
has this already fixed.
The GLib CVS diff is available at
http://cvs.gnome.org/bonsai/cvsview2.cgi?diff_mode=context&whitespace_mode=show&root=/cvs/gnome&subdir=glib/glib&command=DIFF_FRAMESET&file=gmem.c&rev2=1.43&rev1=1.42
This problem renders the zorp package quite unstable under heavy load, and
possibly causes problems with other GLib-based multithreaded software.

glib 2.4 is in experimental now, this fixed is fixed, I'm closing it.
