[PATCH] exec: allow init to exec from any thread.
After looking at the problem of init calling exec some more I figured out an easy way to make the code work. The actual symptom without out this patch is that all threads will die except pid == 1, and the thread calling exec. The thread calling exec will wait forever for pid == 1 to die. Since pid == 1 does not install a handler for SIGKILL it will never die. This modifies the tests for init from current->pid == 1 to the equivalent current == child_reaper. And then it causes exec in the ugly case to modify child_reaper. The only weird symptom is that you wind up with an init process that doesn't have the oldest start time on the box.
