Automatically Limiting Repeated Checking On Completion Of A Command Without Relinquishing A Processor

One or more non-transitory computer-readable storage media storing a plurality of instructions that when executed by one or more processors in a computer cause the one or more processors to:

• use a processor in the thread or process, to issue a command to be executed without use of the processor, wherein the thread or process retains control of the processor after issuance of the command;
• after the thread or process starts running, determine a limit to be imposed on repetitive checking on completion of the command;
• check by using the processor in the thread or process, on whether the current execution of the command has completed, and while the current execution of the command has not completed, without relinquishing the processor in the thread or process, repeating the checking until the limit is reached;
• and
• relinquish the processor in the thread or process, in response to the limit being reached.

An apparatus comprising one or more computer memories coupled to one or more processors in a computer, the one or more processors being configured to execute instructions in the one or more computer memories to cause:

• use of a processor in the thread or process, to issue a command to be executed without use of the processor, wherein the thread or process retains control of the processor after issuance of the command;
• after the thread or process starts running, determine a limit to be imposed on repetitive checking on completion of the command;
• check by use of the processor in the thread or process, on whether the current execution of the command has completed, and while the current execution of the command has not completed, without relinquishing the processor in the thread or process, repeat the check until the limit is reached;
• and
• relinquish the processor in the thread or process, in response to the limit being reached.
