Headacher and NightFlier: yes, no doubt intensive large apps along with other stuff loaded in the background, could reach 2GB of RAM use. I guess gwt will have to decide that if that is the sort of thing he intends to do then he probably should add a swap partition, say 500MB-1GB in size would do it. Maybe I'm just a casual user then because I have 1GB of RAM and have NEVER seen swap being used, no matter what sort of stuff I'm doing....
and yes, you're right, Wine is not really an emulator...
