 * On Linux or MacOs, the free memory metric doesn't include reclaimable file system caches and will thus always report that the system is almost out of memory.
 * Use {@link MemInfoOsMemoryInfo} and {@link NativeOsMemoryInfo} instead.
 * On Windows, this doesn't include the secondary commit limit, which is the maximum amount of virtual memory that can be allocated.
 * Use {@link WindowsOsMemoryInfo} instead.
