I think the pipe blocks because the file handle's buffer fills up. You
don't have any code that reads the data from the file handle. If you
want to buffer all of the output into memory, you'll have to write
code to do that yourself (although it would be better to process the
lines incrementally.)
FYI, in general if you're wondering what a process is taking time
doing, the quickest way to find out is to use Activity Monitor, or the
"sample" command, to sample it for a few seconds .
