- * Check if enough memory is available to proceed.

- * e.g. on systems with little physical swap availrmem can be
- * more reliable indicator of how much memory is available.
- * On systems with large phys swap freemem can be better indicator.
- * If freemem drops below threshold level don't return an error
- * immediately but wake up pageout to free memory and block.
- * This is done number of times. If pageout is not able to free
- * memory within certain time return an error.
