since 10.8.beta6, on ubuntu, I am experiencing strange hangs when trying to recompile sage, for example most recently when doing sage -i dot2tex.
I have no idea how to debug this, here is what make printed last. top tells me that meson is now using all of the cpu. After such a failed recompilation, sage does not start anymore.
