>          Issue Type: New Feature
>          Components: DRLVM
>         Environment: this patch is needed for compiling and executing vmmagic calls (initially
only mmtk contains vmmagic calls, but eventually "vm helpers" could also need it)

>            Priority: Minor

mon_enter_exit.h.diff

> without this patch, the VM will do the wrong thing with vmmagic unboxed objects when
calling the JIT to compile a method.  Because this mod alters heavily used code paths, I thought
it best to put it as a patch first.  Then commit once others are able to successfully use
it.
