run-webkit-tests doesn't start on my machine. This appears the be because the script checks for free memory.

An OS X system is expected to have as close to 0 free memory as possible, because there is no reason to evict stuff from caches before someone asks for memory. Can a better heuristic be found, perhaps based on inactive memory? Can at least one process be always started?

PhysMem: 1146M wired, 3105M active, 3867M inactive, 8119M used, 61M free. VM: 253G vsize, 1122M framework vsize, 81575868(0) pageins, 929707(0) pageouts.
