:mrdocs:

Set the default thread stack size to the specified `numBytes`. If a minimum thread stack size is known for the underlying platform (i.e. `PTHREAD_STACK_MIN` is defined) and `numBytes` is below that minimum, the stack size will be that minimum. The behavior is undefined unless `0 <= numBytes`.
