    It's worth noting that on systems such as linux and solaris, it is easy
    to avoid the paging problem by locking the process into memory. This is
    accomplished using the system calls mlock(2) and mlockall(2). The former
    is probably more suitable as the latter locks all of pages for the
    process. This is of course outside the scope of the C (or other
    language) definition.
