Mem usage in Mac OSX

All the following have this VM ~=4GB on startup -- its not a leaking 
problem... (afaict)

OGL/D3D -- WinRAR, GTAVC, Tribes2, (FlatOutDemo -- even thou it dies on 
startup now -- still gets to ~4GB), SHOGO

NON-GL -- cmd (not even using X11), winecfg, StreamDown, MS VC++ 6, 
MS+Connentix VPC (even thou it uses a driver and will not start correctly), 
Shogo (start screen)

It just plain takes too much mem -- then dies due to the OS saying 
(I will have to test top at some point...)

Does Linux have the same mem problem? -- does top show like 4GB of VSIZE on 
app start?
