// lock is held by the caller. This key can be used in conjunction with
// transactions to safely ensure updates to etcd only occur while holding
// lock ownership. The lock is held until Unlock is called on the key or the
// lease associate with the owner expires.

// be treated as a single acquistion; locking twice with the same lease is a
// no-op.
