Single site import never shows complete

Doing a server move and using mass transfer for small site, but larger sites always seem to fail / crash old server, so doing manual backups using nice -n 19 and compression of 1.

When I go to import these sites it seems to work fine, but the import page never shows that it imports. It just still sits the spinning.

Is this still an issue? I haven’t seen it happen since I’ve been running mass imports, though thanks for the nice level to run backups on super-slow old machines. That’ll be handy in the future.
