Log message:
Make it possible to convert map arguments to long and insert nsecs in maps.
Necessary to measure latency, example below to better understand the kqueue
select(2) regression:
syscall:select:entry { @start[pid] = nsecs; }
syscall:select:return { @usecs = hist((nsecs - @start[pid]) / 1000); }
