        * defineclass.cc (_Jv_ClassReader::handleCodeAttribute):
        Initialize thread_count.
        * include/java-interp.h (_Jv_InterpMethod::thread_count): New
        field.
         (_Jv_InterpMethod::rewrite_insn_mutex): New mutex.
        (_Jv_InterpFrame:: _Jv_InterpFrame): Pass frame_type.
        * interpret.cc
        (ThreadCountAdjuster): New class.
        (_Jv_InterpMethod::thread_count): New field.
        (_Jv_InitInterpreter): Initialize rewrite_insn_mutex.
        Increment and decrement thread_count field in methods.
        * interpret-run.cc (REWRITE_INSN): Check thread_count <= 1.
        (REWRITE_INSN): Likewise.
        Declare a ThreadCountAdjuster.
