6Once you are dealing with a runtime that reserves the right to stop the world and do garbage collection, you aren't really "real time". You can likely engineer something that will generally work within your constraints most of the time, but when you say things like "never" deviate more than 5%, it's harder to make those promises.– Marc TalbotCommented May 17, 2019 at 19:00

Good point. I guess when I say never, what I mean is really rare. So if GC takes up an entire second once a year I can live with that. Is there any good way of gathering statistical data?– James StrieterCommented May 17, 2019 at 19:08

There are different types of real-time systems. Soft real-time systems allow some deadlines to be missed. In audio processing specifically, many systems use a buffer to allow for missed deadlines. Real-time garbage collection is also an area of active research.– Rein HenrichsCommented May 17, 2019 at 21:17

- Always respect the author’s intent
- Don’t use edits to reply to the author
How to Format
-
create code fences with backticks ` or tildes ~
```
like so
``` -
add language identifier to highlight code
```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes
`like _so_` - quote by placing > at start of line
- to make links (use https whenever possible)
<https://example.com>
[example](https://example.com)
<a href="https://example.com">example</a>
How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
