More than some sympathy is in order.

Consider that OS, utility, application or hardware updates can hide or
break such things.

Even if the magic was hidden in RenderMan software under their (Pixar)
control knowing
and getting the correct version of shared system libraries that were
invoked can be a daunting task.

Pixar has done some parallel programming and parallel programming can be
subtle in its instability
as the system is interrupted and work units are merged in slightly
different orders.  Deterministic
work in parallel is sometimes hard.
