Honestly I'm not sure whether this is possible in practice.
In theory it certainly is, and we already have the code.
It really depends on how well the GC code can code with being put into
an environment like this.
See the CNI (and JNI) invocation API. These can be used to load
libgcj dynamically and start up a Java virtual machine in an existing
process. However, based on the small number of bug reports, I'd say
this hasn't been heavily used (or it is very well implemented :-).
