Just an idea: perhaps scan_busylist should move a process to a different list (the error list?) after treating it with proc_kill_force? Currently the processes on the busy list are never checked for being a zombie. With the proposed change they should be correctly reaped after all the waiting and killing. -- Andriy Gapon
