When converting a docx to pdf, containg large number of runs, the default RPr is deep-copied using marshalling and unmarshalling multiple times for a single document. To save this time, we can deep-copy the default RPr once and save it in thread local. After each iteration of using RPr element, it can be set to default, using the initial conditions(obtained from default RPr).
