           Summary: deadlock in
                    System.Object.__icall_wrapper_mono_array_new_specific
           Product: Mono: Runtime

Full details and gdb lock debugging below. Note that only one thread has only
one lock held - so there should be no deadlock. The
GLib.MainLoop.g_main_loop_run is probably due to a glib.idle.add run from the
SignalHandler. However I am using mono-1.9.0-pre4 and UnixSignal.WaitAny() so
there should not be any deadlock due to signal-handler.
