[nsp] RED_ZONE Limit?

red zone is an intentionally unused memory space (boundary) between allocated memory blocks, initialized with a well-known value. if the code somehow manages to overflow the buffer there is a large probability that also the redzone will be overwriten

memory manager processes periodically scan all redzones for proper values. should they find a discrepancy, that usualy denotes a buffer overflow error, in this case in the packet processing code
