When an allocation has been created, it is still being created in the background. The client may request deletion of the allocation *prior* to the creation of the allocation is entirely completed. That is fine, but the challenge is we may encounter a locked row if we're asked to delete while in process. So, we'll query with with_for_update[0] which should be held until the lock is released, which is only released when the original locking transaction closes out[1][2].

Overview
Ironic consists of an API and plug-ins for managing and provisioning physical machines in a security-aware and fault-tolerant manner. It can be used with nova as a hypervisor driver, or standalone service using bifrost. By default, it will use PXE and IPMI to interact with bare metal machines. Ironic also supports vendor-specific plug-ins which may implement additional functionality.
