Does that mean we need the suspension check (and suspend) at other locations?

I am looking at `JRT_ENTRY` and it uses `ThreadInVMfromJava` - so why are we not checking for suspension in that transition somewhere, or else somewhere directly in the JRT_ENTRY? I guess maybe not all JRT_ENTRY points are safe for suspension? But then how do we know all the callers of `get_jvmti_thread_state` are safe for suspension?
