Comment (by dd32):

 My initial thoughts on this were that Long-running functions (such as
 `copy_dir()` and `unzip_file()`) could execute a action every iteration,
 such as `upgrader_tick`.
 A function hooked to that could then echo `<!-- Some data -->` every x
 seconds, If we had a method which left the FTP connection idle for a
 decent amount of time, we could also send a FTP NOOP command every x
 seconds.

 Further to the last point, a FTP NOOP command would be good during long-
 running HTTP downloads when doing bulk upgrades, to keep the connection
 open.
