Unfortunately it does not work...
kpsignal2() ignores attempts to send signals before we are actually
running in the new context:
* If the process is being created by fork, is a zombie or is
* exiting, then just drop the signal here and bail out.
if (p->p_stat != SACTIVE && p->p_stat != SSTOP)
so we can not do the handling earlier, w/o duplicating some of the signal
handling stuff, which we likely do not want to do.
Anyone got better ideas than copying the x86 code over to all child_return
