\section{Worksharing Constructs Inside a \kcode{critical} Construct}

The following example demonstrates using a worksharing construct inside a \kcode{critical} 
construct. This example is conforming because the worksharing \kcode{single}  
region is not closely nested inside the \kcode{critical} region. A single thread 
executes the one and only section in the \kcode{sections} region, and executes 
the \kcode{critical} region. The same thread encounters the nested \kcode{parallel} 
region, creates a new team of threads, and becomes the primary thread of the new team. 
One of the threads in the new team enters the \kcode{single} region and increments 
\ucode{i} by 1. At the end of this example \ucode{i} is equal to 2.
