Creating an addon that provides an uv_hrtime() binding would be a good
cross-platform solution for this.
I don't mind adding a `process.hrtime()` function, it would be useful
for benchmarks. The problem is that uv_hrtime() returns a 64 bits
unsigned integer, while JS numbers only have 53 bits of precision.

But a tuple of 2 JS numbers has 106. This wouldn't be the prettiest API but
it would get the job done.
