cmd/pprof: tool should nuke temporary directories when done #13863
Description
Using go1.5
Calling web on go tool pprof creates a temporary directory, but forgets to clean it up.
Currently, I see:
rawr@carbonite: /tmp $ ll pprof-*
pprof-258052144:
total 0
pprof-316027049:
total 0
pprof-394800818:
total 0
pprof-675261706:
total 0
pprof-871857163:
total 0
...
I expect to see:
rawr@carbonite: /tmp $ ll pprof-*
ls: cannot access pprof-*: No such file or directory
Probably just a missing defer in cmd/pprof/internal/commands/commands.go.
