With current implementation, printing progress while writing a compressed data chunk might be very inaccurate. Thus, for compressed dump segments skip progress_print() in write_addr_range() and call it after each compressed memory chunk is written to disk. For that change write_addr_range() to call progress_print() conditionally based on the new print_progress parameter. For non-compressed dump segments, call progress_print() from write_addr_range() just as before.
