If your OpenGL applications or the libraries that they depend
on are using any of the COMPAT4X signal syscalls, then they
won't work with libthr or libkse.  The COMPAT4X stuff in the
kernel destroys %gs which libthr and libkse both rely on
for their own use.  Are you sure that all your applications
and libraries are rebuilt under -current?  You can try
rebuilding your kernel without COMPAT4X and see if any
of your applications stop running; this will tell you
they need to be rebuilt.
