provided Graal-native versions of os.Native functionality including Native.currentTimeMicros(). The impl in that ticket relied on a Graal Linux/Darwin substitution which provided an impl of System.nanoTime() via access to high-quality timers (if available) with a fall back to gettimeofday() if not. This is a reasonable approach for an initial iteration but it does tie us to the impl of the substitution (and thus to Graal internals) which can change without our knowledge.
This ticket is intended to reconsider the idea of calling gettimeofday() directly instead. This was abandoned for due to some issues with the interaction with the C layer... see if we can resolve this issues with this ticket.
