Better than with swap. This is production workstation - I cannot test something on it :-(

Sorry, I even marked $subject as [OT]. I'm answering the question '2.4 without swap' - Yes. It is. Works. No problems.
<rant>'Paging like crazy' became for me a synonym of Linux. It doesn't matter how much memory you have. Less == worse. Developers stopped testing VMM regression on low-memory computers long time ago. <sarcasm>We have now fashion for clusters and numas. And a lot of swap on very fast raids. <sarcasm size=+100%>After all it is cheap. Just couple of thousands greenbacks. </sarcasm> </sarcasm> It was really funny when developers on LKML were sugesting to buy another hdd for swap. Very funny.</rant>
Unfortunately I'm not a specialist in VMM... As I see there is not that much edge case testing going around.
