...except that madvise() is compliant to at least one of the standards
(either BSD or SVR4). And it's generally better, for the portability's
sake, to stick to some standard instead of producing one more.
Another solution would be:
1. To implement a system call with many arguments handling all
nitty-gritty of the memory allocation policy.
2. To implement madvise() in terms of the aforementioned system call.
