GIOs high-level APIs don't support pausing in the middle of a file.
IMHO this is too much of an advanced feature for thunar. It'll
complicate the transfer operations code and progress dialog quite

not ignoring updates at all even if the progress is minimal. I'm not
sure that would be a good decision though.
