Cancelling an unbond?

Is there a way to cancel an unbond command after the command has been issued? I see that gaiacli implements the gaiacli stake unbond begin and gaiacli stake unbond complete commands.

begin or complete unbonding shares from a validator

Usage:
  gaiacli stake unbond [command]

Available Commands:
  begin       begin unbonding
  complete    complete unbonding

Flags:
      --account-number int   AccountNumber number to sign the tx
      --async                broadcast transactions asynchronously
      --chain-id string      Chain ID of tendermint node
      --fee string           Fee to pay along with transaction
      --from string          Name of private key with which to sign
      --gas int              gas limit to set per-transaction (default 200000)
  -h, --help                 help for unbond
      --json                 return output in json format
      --ledger               Use a connected Ledger device
      --memo string          Memo to send along with transaction
      --node string          <host>:<port> to tendermint rpc interface for this chain (default "tcp://localhost:26657")
      --print-response       return tx response (only works with async = false)
      --sequence int         Sequence number to sign the tx

Global Flags:
  -e, --encoding string   Binary encoding (hex|b64|btc) (default "hex")
      --home string       directory for config and data (default "/home/ubuntu/.gaiacli")
  -o, --output string     Output format (text|json) (default "text")
      --trace             print out full stack trace orors

Use "gaiacli stake unbond [command] --help" for more information about a command.

Cancelling unbonds will be implemented postlaunch. https://github.com/cosmos/cosmos-sdk/issues/577
