Is saving the stack pointer around method handle calls still needed?

Doug Lea reminded Brian, David, and me today of one big reason tail calls are important:  Certain threaded frameworks cannot delegate from one actor to another without it.  The failure mode is stack overflow, very occasionally.  This is the root cause of a recent bug in our fork-join framework code, which schedules from task to task by (sometimes) delegating from the old task to the new one.
