I'll try to investigate if I can easily use sigusr1 with your new patch,
meanwhile I came up with a patch adding status=progress.

It's a simple draft and I am open to hear all comments about it,
especially on what's the format to report the progress.

For example qemu-img uses '\r' so that the output is always on the same
line.

Patch in attachment.
