I briefly skimmed the thread and didn't find the reason why the API
requires an absolute time.
My expectation would be for the last parameter to be a relative timeout
("wait up to X microseconds"). That avoids the annoyance of creating a
new definition of absolute time and exposing a new function to retrieve
it.
