Okay, got it. This sandbox script simulates a blocking call (sleeping for 2 seconds in this case) in a backgrounded subshell, which signals when it's done. Thanks Nicholas!
Oh crap. This won't work because the subshell needs to open a file descriptor that my parent shell wants to read from. This method works great for getting around the blocking issue, but now I need to actually read from the FD opened in the subshell (which gets closed when the subshell exits).
