Add a new element to an array without specifying the index in Bash

... documentation states that the SemaphoreSlim is a lightweight alternative and doesn't use Windows Kernel semaphores. This resource states that the SemaphoreSlim is much faster. In what situations does the SemaphoreSlim make more sense over the Semaphore and vice versa?

I'm trying to run two AsyncTasks at the same time. (Platform is Android 1.5, HTC Hero.)
However, only the first gets executed. Here's a simple snippet to describe my problem:

Detect 7 inch and 10 inch tablet programmatically
...= metrics.heightPixels;
This will return the absolute value of the width and the height in pixels, so 1280x720 for the Galaxy SIII, the Galaxy Nexus etc.
This isn't usually helpful on its own, as when we're working on Android devices, we usually prefer to work in density independent pixels, dip....
