Don't know, I never used valgrind with sigaltstack coroutines. All
examples that I found for the stack registration functions were using it
in the context of ucontext, but I wouldn't be surprised if sigaltstack
needs it as well. If you care enough, you can try it out and send a
patch, otherwise we can still add it when someone needs it.
