Serializing closures

[balaban ittai]

Ok. I think I got things sorted out. It turns out that the biggest problem
in serializing Scheme stuff was that I some of the code was being
interpreted and wasn't precompiled. This caused the whole Kawa package to
be serialized along with my stuff.

So basically, to make things serialize I had to change a bunch of class
declarations to make them implement java.io.Serializable. Also, I had to
add a few public no-arg constructors to some classes in gnu.bytecode. I'd
like to know if this stuff can go in the distribution. How do I
organize these patches?
