This function is currently experimental. Its main use is to judge
the quality of the underlying timer implementation of the
operating system. The function measures the overhead of timing a C
function call rounds times and returns all non-zero timings
observed. This can be used to judge the granularity and resolution
of the timing subsystem.
microtiming_precision(rounds = 100L, warmup = 2^18)A vector of observed non-zero timings.
Number of measurements used to estimate the precision.
Number of iterations used to warm up the CPU.
