.SH DESCRIPTION
.sp
MPI_T_finalize() finalizes the MPI tool information interface and must
be called the same number of times as MPI_T_init_thread() by the end of
execution. Calls to MPI tool functions are allowed at any point in
execution as long as MPI_T_init_thread() has been called at least once
and the number of calls to MPI_T_init_thread() is greater than the
number of calls to MPI_T_finalize(). If at any point in execution the
number of calls to MPI_T_finalize() equals the number of calls to
MPI_T_init_thread() the MPI tool interface will no longer be available
until another call to MPI_T_init_thread().
.SH NOTES
.sp
Before the end of execution the number of calls to MPI_T_init_thread()
and \fI\%MPI_T_finalize\fP must be the same.
