412896 - Timers dropping to 0ms

Status: RESOLVED WORKSFORME

(Core :: DOM: Core & HTML, defect)

Description

[John Resig]

There are a number of instances where when using setTimeout or setInterval (with a delay of 0ms or 10ms) the delay between function calls will randomly drop to 0ms.

See the following graphs for context:

http://ejohn.org/files/timers-10.png
http://ejohn.org/files/intervals-0.png

and the blog post in the URL.

The expected result is that there remains, at least, some sort of delay between the calls, rather than none.
