aM Normalize DTrace output for comparison.
DTrace keeps a per-CPU buffer, and when showing the fired probes, buffers
are concatenated. So if the operating system moves our thread around, the
straight result can be "non-causal". So we add timestamps to the probe
firing, sort by that field, then strip it from the outputz\[[0-9]+ refs\] # c t | d S )Nr )int)rows r <lambda>z(normalize_trace_output.<locals>.<lambda>& s CAK r
