1. A system for performing processor executable instructions comprising: one or more processors; an activity object initialized by the one or more processors in response to receiving a request, the activity object allocating a context memory and including a queue structure stored in the context memory; and an operation segment configured to initiate at least one input/output (I/O) action, add a reference to a next operation segment to the queue structure of the context memory upon completion of the at least one I/O action, and initiate execution, by the one or more processors, of an operation segment at a head of the queue structure of the context memory, execution of the operation segment at the head of the queue structure initializing at least a second I/O action and adding a reference to a second operation segment associated with completion of at least the second I/O action to the queue structure of the context memory.
