Sorry, which bit of code are you talking about now, re: the ppid?

Incidentally, I can't help but wonder whether all this effort of
managing locking and the clipboard is far more complex than just having
pass not exit until it's reset the clipboard. The interface would be
something like:

  mattcen at owen:tmp$ pass -c example
  Copied example to clipboard. Will clear in 45 seconds.
  Hit Ctrl+C to clear and exit immediately

And just put in a trap on SIGINT that clears the clipboard before

Have I missed something? Is there a good reason for pass to return
control back to the shell before you've pasted the password?
