    Description

      JNI calls a pair of hythread_suspend_enable() and hythread_suspend_disable() every time the transition occurs. That lead to serious overhead due to calls.
      The idea is to inline these methods by implementing two mnemonics in LIL - hse() and hsd(), then LIL codegenerator will generate the code for them. More solid solution should inline method calls in LIL, but it's too complex to achieve.
