  • In some ways this model could actually be more secure against PID reuse than pure sequential, because it causes PID reuse to be extreamly common, and quickly grabbed, this has two effects 1) It means any software that incorrectly depends on PIDs not beign reused is more likely to fail observably and be patched, 2) The OS is likely to assign the PID to something other than what the attack wants before the attacker does, making attacks harder to pull off.
