finish_current_insert and del_pending_extents process extent tree modifications that build up while we are changing the extent tree. It is a confusing bit of code that prevents recursion. Both functions run through a list of pending operations and both funcs add to the list of pending operations. If you have two procs in either one of them, they can end up looping forever making more work for each other. This patch makes them walk forward through the list of pending changes instead of always trying to process the entire list. At transaction commit time, we catch any changes that were left over.
