Maybe this commented code could go?

@dolio are all these implementable in Chez land? (This is something we should always ask ourselves for new builtins I think) |

This adds a few builtins for nanosecond-precision clocks.
realtimereturns the civic time as nanoseconds since epoch.monotonicreturns a number of nanoseconds since an arbitrary point in the past, guaranteed to monotonically increase on subsequent calls. This is unaffected by time changes and other processes changing the system clock.processCPUTimereturns the amount of time spent in the Unison process running the program.threadCPUTimereturns the amount of time spent in the OS thread running the program.
