Returns the estimated number of ticks per second. This feature

<para>
This function may take several milliseconds or more to execute
in order to calculate a good estimate of the number of ticks (as
measured by the profiling functions) per second. Note that the
number of ticks per second is often dependent on the CPU frequency,
which can change dynamically. Thus the value returned by this
function may be incorrect as soon as it is returned.</para>
