Description

The getItem call generates extra existence verification calls for both property and nodes, which also happen in the delegate #create calls.

The simplification I'm proposing also has some perf gains:

-- before:
# ReadDeepTreeTest               min     10%     50%     90%     max       N

# ConcurrentReadDeepTreeTest     min     10%     50%     90%     max       N

-- after:
# ReadDeepTreeTest               min     10%     50%     90%     max       N

# ConcurrentReadDeepTreeTest     min     10%     50%     90%     max       N
Oak-Tar                         1909    1997    2244    2498    2616      27
