Details

The thread VsyncIOThread [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.

I'm going to mark these threading bugs as low priority for now, absent a clear indication of how important/useful we consider this effort.

Priority: -- → P3
