I would find this argument more persuasive if we didn't have a
ton of other places where we call abort() or assert() or
g_assert_not_reached(). Either we should have a consistent
mechanism for assertions in linux-user turning off the SIGABRT
handler, or we should just not worry about it on the basis that it's
a "can't happen" error anyway...
thanks
