Package spin provides objects for assisting with sleeping while waiting for
an action to become available. This is useful in preventing CPU starvation
when there is nothing to do.
type Sleeper struct {
// contains filtered or unexported fields
}
Sleeper allows sleeping for an increasing time period up to 1 second
after giving up a goroutine 2^16 times.
This is not thread-safe and should be thrown away once the loop the calls it
is able to perform its function.
Sleep at minimum allows another goroutine to be scheduled and after 2^16
calls will begin to sleep from 1 nanosecond to 1 second, with each
call raising the sleep time by a multiple of 10.
