Perhaps it might be easier to do this test in reverse - modify the memory in child instead. This would be nicer, as it would only require waitpid sync point, without sleep. But I'm not 100% sure that such approach would test exactly the same thing

I'll add separate test case for that
pages_in_child_copied test checks if pages with protection changed to read from read-write by mprotect are copied by child. pages_in_parent_copied test checks if pages with protection changed to read from read-write by mprotect are copied by parent. JIRA: RTOS-953
