2. replace BufferedWriter used by Serializer with an unsynchronized custom version, enabling much better compiler inlining
I've confirmed this. It's a noticeable improvement. A version of this is now in CVS. It's a bit of a surprise. I thought synchronization wasn't supposed to have such a huge impact in modern VMs.
I experimented with several variations but I ended up committing basically what Wolfgang submitted modulo some refinements to fit my coding conventions that I don't think have any impact on the byte code. I'll look at the other changes as time permits. Thanks!
