A really useful addition to gcj,  with respect to GC integration, would
be to implement a configurable `write_barrier' RTL pattern inside the .md
file.  Just invoke this pattern whenever making an assignment to an object
reference.  I'm doing this myself in my own embedded port of gcj, but it
would be really nice to have this integrated into mainstream code.
