Looking into it a bit, I'm surprised to find that even ThreadInfo
doesn't really have information about this. But I guess it makes
sense as the thread isn't really blocking on IO until it's in the
kernel and out of the VM's control.
I think you'd actually have to dig out a native thread ID and use
whatever native facilities there are for querying a thread's wait
state and/or tracing when it enters a blocking system call.
