What is a latency-sensitive application?

I am reading the book "Linux Kernel Development" by Robert Love. I found that the O(1) Scheduler (it was a task scheduler for Linux) had failures managing latency-sensitive applications. What is a latency-sensitive application?

Latency means time delay. latency-sensitive application would therefore mean that those apps would respond immediately.

A latency-sensitive application is an application which needs to react "fast" on specific events. Latency is defined as the time between the occurence of an event and its handling. Example: a media/streaming player needs to react "fast" to incoming media-pakets (network/file) to transform them and bring them somehow to the audio-output. If you have high latency in this process you will have drop-outs in your player. I had the quotes around "fast", because in most cases you want to have a detreministic behaviour, but most people expect it to be "fast".
