 Where is the kernel code hiding that causes this for the forkee?
 
 I see the code for the process calling fork() at the end of
 kern_fork.c, but the "child2" process does not run that code, and I
 don't understand how it works on amd64. nxr does not find other kernel
 referencs for TRAP_CHLD (and this one works, the forker properly gets
 signaled).
