Return an object giving memory usage statistics about the current process. Note
that all statistics are reported in Kilobytes.
* `workingSetSize` - The amount of memory currently pinned to actual physical
RAM
* `peakWorkingSetSize` - The maximum amount of memory that has ever been pinned
to actual physical RAM
* `privateBytes` - The amount of memory not shared by other processes, such as
JS heap or HTML content.
* `sharedBytes` - The amount of memory shared between processes, typically

### getSystemMemoryInfo()
Return an object giving memory usage statistics about the entire system. Note
that all statistics are reported in Kilobytes.
* `total` - The total amount of physical memory in Kilobytes available to the
system
* `free` - The total amount of memory not being used by applications or disk
cache
