If stub terminates right after execution, e.g. due to lack of system resources (requested number of cpu cores to run on, right amount of memory, etc.) start_stub() would end up blocking forever since there wouldn't be any entity around that would mknod spdk_stub0 for it to break the loop. Avoid the above scenario by checking if $stubpid is still visible under procfs and return if it goes missing. To make sure kill_stub() is still called to clean up after start_stub() declare proper trap prior the call to start_stub(). Additionally, avoid potential stderr noise in case kill|wait are told to act on a PID that's not visible in the ns anymore.
