issue

torusctl block dump doesn't finish with progress output

reproduction steps

1. create volume

./bin/torusctl  -C 192.168.121.1:2379 volume create-block myvolume 1GiB
./bin/torusctl  -C 192.168.121.1:2379 volume list
VOLUME NAME  SIZE     TYPE
myvolume     1.0 GiB  block

2. dump volume with --progress option

./bin/torusctl  -C 192.168.121.1:2379 block dump myvolume foo
myvolume [===================================================] 1.07 GB / 1.07 GB

Then, the dump stuck with above output.

additional information

• without --progress option, the command works well.
• torusctl block load --progress has same issue.
