Help explanation for --poll under nova commands is not clear

[Dafna Ron]

root@puma32 ~(keystone_admin)]# nova help image-create
usage: nova image-create [--poll] <server> <name>

Create a new image by taking a snapshot of a running server.

Positional arguments:
  <server> Name or ID of server.
  <name> Name of snapshot.

Optional arguments:
  --poll Blocks while server snapshots so progress can be reported.

I am not sure what "Blocks while server snapshots so progress can be reported."
blocks what? :) I can't understand if --poll should do anything more than report the progress.

The same applies to others nova commands: boot, migrate, resize, rebuild and reboot.
I will change the title to show that too.
