How to cancel pending actions in Client Context? (Managed Client Object Model)

Question

I have written a code relying on Managed Client Object Model which performs the following actions:

1. Creates a site Web site
2. Creates a list List list1
3. Creates a list field FieldText field1 (which is a field of list1 list)
4. Creates a list field FieldNumber field2 (which is a field of list1 list)
5. Creates another list List list2
6. Calls clientContext.ExecuteQuery() which orders the SharePoint to actually create all these SharePoint components.

I want to achieve the following:
If for some reason something goes wrong while creating field2, i.e. in the step 4, I want my code to cancel the creation of list1, field1 and field2, but I still want the site and list2 to have created.

I see the clientContext as a kind of a container where I can stack my commands and then call the ExecuteQuery method which processes these commands, i.e. pushes them to SharePoint. If I am correct, then my problem is that I am unable to clear certain commands stacked inside the clientContext object. I need to have them removed before the query gets executed. Can you show me how? Thanks.

That can be done using batch exception handling. Take a look at:
