child_signal_init is reasonably heavyweight in that it keeps a couple of 
file descriptors open, so the idea is to be lazy and not call it unless 
Emacs plans to have children.

I installed the attached, which is like Robert's patch except it keeps 
the critical section smaller and checks the declaration of the 
now-extern function. Please give it a try. I'll boldly close the bug 
report; we can reopen it if I'm wrong.
