ManagedWorkspace2D Memory limit: add an option to use the total Swap+Physical memory (mostly for Linux)

Reported by: Janik Zikovsky Owned by: Janik Zikovsky
Priority: major Milestone: Iteration 30

Description

ManagedWorkspace2D kicks in too early on Linux due to odd memory reporting... If instead we use a percentage of the total available memory (disk swap + physical), we can let Linux use its own (better) swapping until it becomes impossible.

This is no longer really needed as long as you use TCMalloc. Swap is likely to be slower than ManagedWorkspace2D (since the whole darn system grinds to a halt).

Tests have previously proved (at least on 32 bit windows) that managed worksapces are notably faster than swap and can handle larger volumes.
