📄 Description

The GPU drivers take a while to update their free memory reporting, so we need to wait until the values converge with what we're expecting before proceeding to start another runner in order to get an accurate picture.

Prior to this fix, this can manifest as loading less layers than expected on a subsequent load and seeing slow inference, or worst case, toggling back and forth between GPU and CPU.

Fixes #4253
