I don't see how this could possibly work if the
managed code objects you are trying to persist deal in
any way with resources outside of the managed world. 
For instance, I assume threads are implemented as
either some pthreads based objects or some windows
threads objects (in the kernel sense of the word
object, of course) and you cannot possibly expect
anything running in the managed world to know how to
"persist" these things unless the managed objects
specifically know how to do this (i.e. are designed to
support this functionality).

Or am I missing the point?
