Since profile/cProfile CLI interface prints a sorted list of stats, using head to limit output to the most relevant entries should be a fairly natural thing to do. Unfortunately, BrokenPipeError isn't caught, causing quite a bit of pollution to the output:
$ python3 -m cProfile -m http.server -h | head
usage: http.server [-h] [--cgi] [--bind ADDRESS] [--directory DIRECTORY]
[port]
positional arguments:
port Specify alternate port [default: 8000]
optional arguments:
-h, --help show this help message and exit
--cgi Run as CGI Server
--bind ADDRESS, -b ADDRESS

BrokenPipeError: [Errno 32] Broken pipe

BrokenPipeError: [Errno 32] Broken pipe
I think the exception should be caught in order to suppress this noise.
