For reference, similar code under Java consumes 2.5 % CPU.
I tested the Go code under OSX, and it is roughly 10%, which seems to be very
high. Might be because the “context switching” is performed/attributed to the
process (since it is internal), where for other systems it is the system call
only, and so most of the cost is attributed to system/kernel activity.
