127 This option allows measurement of each thread's stack by initializing
128 it to a predefined value at thread creation time. Later use of the
129 cyg_thread_measure_stack_usage() function allows the maximum stack
130 usage of the thread so far to be obtained. Note that this is not
131 necessarily the true maximum stack usage that the thread will ever
132 use since all that has been measured is the stack usage corresponding
133 to the code path followed this time, and not the code path that may
134 be followed in future."
