Exiting Batch Synchronisation Section in Cleanup

Hi,
I have a test sequence which uses Batch Synchronisation in the following way:
1. Entering Batch Serial Section
2. Enter Batch One Thread Only Section
3. Set Temperature
4. Exit Batch One Thread Only Section
5. Test
6. Exit Batch Serial Section

I also use SequenceFilePostStepRuntimeError callback in the way that when error occurs ProcessCleanup callback is executed.

Now I want to know how to properly exit batch synchronisation section eg when error occured in step 3 or in step 5. I tried to access those steps ResultStatus properties but without any success (I mean they were always empty). I used: RunState.SequenceFile.GetSequenceByName("MainSequence").GetStepByUniqueId("ID#:wkly0AIqzUWmRLZ/hRtGVC" /* Enter One Thread Only (Low_Temp_Setup) */).ResultStatus

With status information I could create preconditions when to run which "exit steps".

Result recoding is disabled.

So what is the recommendation for emergency synchronisation exit strategy?
