What is claimed is: 1. A method for locking, comprising: receiving, with a computer including a processor, a request from a client with a first operation identifier to lock a first resource controlled by a first agent; locking the first resource with the first operation identifier, wherein an additional request to lock the first resource with the first operation identifier is granted; determining whether a second resource controlled by a second agent should be locked for the request from the client with the first operation identifier or with a second operation identifier based on whether a lock on the second resource is to be used to enable the request from the client to complete by determining whether an operation to be performed by the second agent for the request from the client is to complete by a time the request from the client is completed; in response to determining that the lock on the second resource is to be used to enable the request from the client to complete, locking the second resource with the first operation identifier, wherein an additional request to lock the second resource with the first operation identifier is granted; and in response to determining that the lock on the second resource is not to be used to enable the request from the client to complete, generating the second operation identifier; and locking the second resource with the second operation identifier, wherein an additional request to lock the second resource with the second operation identifier is granted. 2. The method of claim 1, wherein the request from the client is a first request and further comprising: locking the second resource by sending a second request to a lock manger of the second agent to lock the second resource; and under control of the lock manager of the second agent, determining whether a lock conflict exists; in response to determining that there is no conflict, sending the second request to the second agent; and in response to determining that there is a lock conflict, queuing the second request. 3. The method of claim 1, further comprising: obtaining the second operation identifier.
