Hi All,
I understand this issue has been discussed in the past, and I have seen a 
few comments from Ian and Russ Cox about this topic, but I could not arrive 
at a conclusion about how I can make the time.Ticker send me ticks at 
atleast close to the Ticker duration I specify. At the moment, I am seeing 
ticks being sent at way over the specified duration especially when I have 
sub-millisecond durations. 
With 1ms duration, the ticker seems to be quite close to the duration 
(maybe within +/-5%). I would be happier if it were within 1%, but I can 
handle that.

With 1 micro-second duration, the ticker sends ticks nearly 4 times slower 
than expected.

Here is my sample code
"
ti := time.NewTicker(1 * time.Millisecond)
start := time.Now()
for i := 0; i < 1000; i++ {
<-ti.C
}
fmt.Printf("elapsed time = %v\n", time.Since(start))
"

The output is usually close to 1 second as expected (close to) when using 
1ms duration.
elapsed time = 1.000159338s

But when I change the Ticker duration to 1 micro-second, I get the 
following output which shows the elapsed time close to 4 seconds:
elapsed time = 4.796662856s 
*Is there anyway, I can ensure ticks are sent at approximately within 5% of 
my specified duration ?*

I understand from time.Ticker docs that ticks will be lost if the ticker 
handler cannot keep up with the ticker time.

In the simple code above, I am literally doing very minimal work in each 
loop iteration and that is about checking the loop condition.
So I am not sure why ticks are being lost ?
