/*
* This test tests the actual swap size on linux and solaris.
* The correct value should be checked manually:
* Solaris:
* 1. In a shell, enter the command: "swap -l"
* 2. The value (reported in blocks) is in the "blocks" column.
* Linux:
* 1. In a shell, enter the command: "cat /proc/meminfo"
* 2. The value (reported in bytes) is in "Swap" entry, "total" column.
* Windows NT/XP/2000:
* 1. Run Start->Accessories->System Tools->System Information.
* 2. The value (reported in Kbytes) is in the "Page File Space" entry
* Windows 98/ME:
* Unknown.
*
* Usage: GetTotalSwapSpaceSize <expected swap size | "sanity-only"> [trace]
* This test tests the actual swap size on Linux and MacOS only.
