What @Warluck means is that the tail -F at the LHS of the pipe will not stop immediately once the while read loop at the RHS of the pipe finishes. Instead it will exit at the moment that it tries to write the next line to the pipe and can no longer do that.

tau_mapping_object
TAU_MAPPING_OBJECT(3) TAU Mapping API TAU_MAPPING_OBJECT(3)
NAME
TAU_MAPPING_OBJECT - Declares a mapping object
SYNOPSIS
C/C++:
TAU_MAPPING_OBJECT(FunctionInfo FuncIdVar);
DESCRIPTION
To create storage for an identifier associated with a higher level statement that is mapped using TAU_MAPPING, we use the
TAU_MAPPING_OBJECT macro. For example, in the TAU_MAPPING example, the array expressions are created into objects of a class
ExpressionKernel, and each statement is an object that is an instance of this class. To embed the identity of the statement we store the
mapping object in a data field in this class. This is shown below:
EXAMPLE
C/C++ :
template<class LHS,class Op,class RHS,class EvalTag>
class ExpressionKernel : public Pooma::Iterate_t {
public:
typedef ExpressionKernel<LHS,Op,RHS,EvalTag> This_t;
//
// Construct from an Expr.
// Build the kernel that will evaluate the expression on the
// given domain.
// Acquire locks on the data referred to by the expression.
//
ExpressionKernel(const LHS&,const Op&,const RHS&,
Pooma::Scheduler_t&);
virtual ~ExpressionKernel();
// Do the loop.
virtual void run();
private:
// The expression we will evaluate.
LHS lhs_m;
Op op_m;
RHS rhs_m;
TAU_MAPPING_OBJECT(TauMapFI)
};
