Globally declared variables are allocated in the data segment of a process;
updates performed by a thread on one process are therefore not visible on
other processes. However, any global variables declared and initialized by the
C++ program before the start of the RT++ program are visible in the same way
to all RT++ threads provided that these variables are not modified during the
execution of the RT++ program.
