BugLink: https://bugs.launchpad.net/bugs/2073603

[ Upstream commit 77b79df0268bee3ef38fd5e76e86a076ce02995d ]

Polling is initially attempted with timeout_base_ms enabled for
preemption, and if it exceeds this timeframe, another attempt is made
without preemption, allowing an additional 50 ms before timing out.

v2
- Rebase

v3
- Move warnings to separate patch (Lucas)
