`Stop` methods have not been called.
Earlier versions of Go did not collect unstopped `Timer`s until after
they had fired and never collected unstopped `Ticker`s.

Second, the timer channel associated with a `Timer` or `Ticker` is
now unbuffered, with capacity 0.
The main effect of this change is that Go now guarantees
that for any call to a `Reset` or `Stop` method, no stale values

variable or function.

A reference to a method <code>m</code> is a
<a href="#Method_values">method value</a> or
<a href="#Method_expressions">method expression</a> of the form
<code>t.m</code>, where the (static) type of <code>t</code> is
not an interface type, and the method <code>m</code> is in the
<a href="#Method_sets">method set</a> of <code>t</code>.
