    When this effect represents acquisition of a resource (for example, opening a file, launching a thread, etc.), acquireReleaseWith can be used to ensure the acquisition is not interrupted and the resource is always released.

    When this effect represents acquisition of a resource (for example, opening a file, launching a thread, etc.), acquireReleaseWith can be used to ensure the acquisition is not interrupted and the resource is always released.

    The function does two things:

    1. Ensures this effect, which acquires the resource, will not be interrupted. Of course, acquisition may fail for internal reasons (an uncaught exception). 2. Ensures the release effect will not be interrupted, and will be executed so long as this effect successfully acquires the resource.

    In between acquisition and release of the resource, the use effect is executed.

    If the release effect fails, then the entire effect will fail even if the use effect succeeds. If this fail-fast behavior is not desired, errors produced by the release effect can be caught and ignored.

This is useful to specify a default executor that effects sequenced after this one will be run on if they are not shifted somewhere else. It can also be used to implement higher level operators to manage where an effect is run such as ZIO!.onExecutor and ZIO!.onExecutionContext.

     Returns an effect that suspends for the specified duration.

     Returns a lazily constructed effect, whose construction may itself require effects. The effect must not throw any exceptions. When no environment is required (i.e., when R == Any) it is conceptually equivalent to flatten(succeed(zio)). If you wonder if the effect throws exceptions, do not use this method, use Task.suspend or ZIO.suspend.
