initialize profile only after first cmd

[nsheff]

instead of initilazing right at the beginning, so we end up witht this if no commands are run:

# Pipeline started at 08-12 12:05:20						
						
# pid	hash	cid	runtime	mem	cmd	lock
# Pipeline started at 08-12 12:06:30						
						
# pid	hash	cid	runtime	mem	cmd	lock
# Pipeline started at 08-12 12:06:57						
						
# pid	hash	cid	runtime	mem	cmd	lock
# Pipeline started at 08-12 12:07:14						
						
# pid	hash	cid	runtime	mem	cmd	lock
# Pipeline started at 08-12 12:11:13						
						
# pid	hash	cid	runtime	mem	cmd	lock
# Pipeline started at 08-12 12:14:09						
						
# pid	hash	cid	runtime	mem	cmd	lock
# Pipeline started at 08-12 12:14:28						
						
# pid	hash	cid	runtime	mem	cmd	lock
# Pipeline started at 08-12 12:15:17						
						
# pid	hash	cid	runtime	mem	cmd	lock
# Pipeline started at 08-12 12:17:51						
						
# pid	hash	cid	runtime	mem	cmd	lock
