- pipe size in Linux is only 8*512=4096 bytes - pipe size is not setable - when the feeding process spits out data faster than the eating process can read it, then the feeding process stalls after 4KiB of data sent to the pipe - for us, the progress bar would spawn a sub-shell every line, and the sub-shell would in turn spawn a 'date' command. Which was sloooww as hell, and would cause some kind of a starvation: the pipe was full most of the time, and the feeding process was stalled all this time. Now, we use internal variables and a little hack based onan offset to determine the elapsed time. Much faster this way, but still CPU-intensive.
