* This test is just a sanity check and does not check for the correct
* value. The correct value should be checked manually:
* Solaris:
* 1. In a shell, enter the command: "ps -efly"
* 2. Find your process, and look in the "SZ" column. Reported in Kbytes.
* Linux:
* 1. In a shell, enter the command: "ps -efly"
* 2. Find your process, and look in the "SZ" column. Reported in Kbytes.
* 1. Hit Ctrl-Alt-Delete, select Task Manager, go to Processes tab.
* 2. Find your process and look in the "Mem Usage" column. Reported in
* Kbytes.
* Windows 98/ME:
* Not supported.
