just an oversight -- should be easy to replicate final_procs
functionality there -- I'll add it to my list, or accept your patches
if you get to it first..

cntr gets initialized in SchedProcess::InitLinks, so it should be
set.. perhaps you have a process type that overloads InitLinks but
doesn't call SchedProcess::InitLinks..
