Two fold commit:
1) Enhance write speed significantly on RMW media like CD-RW, DVD-RW but also
on the DVD+RW and all other ECC blocked media. Significant speedups of access
to the device for say compilation on the DVD. Streaming copy is also still at
maximum speed though vast amounts of directory copy work can show side effects
that appear it to slow down but are actually logical when you consider that
most small files are embedded into the descriptors itself.
2) explicit wait for the created RMW thread to spinup
