Without further ado, the following was found:

Issue:     I<init> → B<init>

"When a new thread is created, the two timer slack values are made the same "
"as the \"current\" value of the creating thread.  Thereafter, a thread can "
"adjust its \"current\" timer slack value via B<PR_SET_TIMERSLACK>.  The "
"\"default\" value can't be changed.  The timer slack values of I<init> (PID "
"1), the ancestor of all processes, are 50,000 nanoseconds (50 "
"microseconds).  The timer slack value is inherited by a child created via "
"B<fork>(2), and is preserved across B<execve>(2)."

I've documented it as B<init>(1).  Thanks!
