f08f4a476a [*] Ehhh. I never liked how I implemented the fallback for MS absolute waits.
We should calculate it via a delta between current NS time to avoid NS/MS clock overflows.
Some platforms and points in time may be more resistant than others. Let's assume monotonic time could be really high, this should help mitigate some bad math and branching caused by timeout overflows caused by stupid MS-precise abs waits (not sure why people would favour these over abs ns)
