1. In a managed code computing environment which implements garbage collection, a system for controlling garbage collection operations, the system comprising: one or more processors; and one or more computer-readable media, wherein the one or more computer-readable media comprise computer-executable instructions that when executed by at least one of the one or more processors cause the system to perform the following: initializing garbage collection to collect objects that are no longer in use for a particular managed code in a managed code environment; receiving managed code including receiving managed code input specifying a desired quantum within which it is desired that no garbage collection will be performed in order to at least increase the performance of the managed code within the desired quantum; performing a computing operation to determine the desired quantum can likely be met, the computing operation including at least evaluating an anticipated resource usage rate of the managed code within the desired quantum; and based at least on determining the desired quantum can be met, running memory operations within the quantum without running the initialized garbage collection.
