What else is .NET? (OK, it's a bunch of other stuff too, but processors like the Itanium that introduce serious system specific performance issues (like memory and cache latencies) are a very good reason to persue dynamic recompilation technologies like HotSpot, Dynamo, FX-86, Transmetta and .NET.) -- Andrew To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
