1620379 - Convert the thread 'GraphRunner' to use the background thread pool

Status: RESOLVED INVALID

(Core :: Web Audio, task)

Description

[Kris Wright :KrisWright]

The thread GraphRunner [1] uses the NS_NewNamedThread method, so it might be possible to move it to the background thread pool.

In an effort to reduce the number of ad-hoc threads in the browser, we want to convert instances of NS_NewNamedThread to use the background thread pool [2] wherever possible. If your thread may block, you can also include the NS_DISPATCH_EVENT_MAY_BLOCK flag.

GraphRunner is a high priority media processing thread. I don't think the work it does is suitable for the background thread pool.
