+The nocache tool tries to minimize the effect an application has on
+the Linux file system cache. This is done by intercepting the open and
+close system calls and calling posix_fadvise with the
+POSIX_FADV_DONTNEED parameter. Because the library remembers which
+pages (ie., 4K-blocks of the file) were already in file system cache
+when the file was opened, these will not be marked as "don't need",
+because other applications might need that, although they are not
+actively used (think: hot standby).
+Use case: backup processes that should not interfere with the present
+state of the cache.
