--------------------------------------------------------------
Attached patch reduces the number of {{AbstractRoot#getRootState}} calls per
query to 1 (from 3) by introducing a execution context within which the query
is executed. This doesn't seem to have an impact on the performance of the xml
import though. Maybe the patch is useful otherwise however since it make the
state used to execute the query against more explicit. [~tmueller], WDYT?
*Update*: I forked this into a separate issue OAK-1052
was (Author: mduerig):
