A few special functions convert between Go and C types
by making copies of the data. In pseudo-Go definitions:

	// Go string to C string
	// The C string is allocated in the C heap using malloc.
	// It is the caller's responsibility to arrange for it to be
	// freed, such as by calling C.free (be sure to include stdlib.h
	// if C.free is needed).

The definition of data-race-free programs and the guarantee of sequential consistency
for race-free programs are equivalent to the ones in that work.

The memory model describes the requirements on program executions,
which are made up of goroutine executions,
