- OSC 52 is ignored: any output, cat'd or remote, could plant a command
on the clipboard to paste
- kill(): terminate(force=True), so a child ignoring HUP and INT does
not outlive its tab with the pty open
- reader pauses once 64 unparsed reads wait, so a large dump blocks the
child at the pty instead of being buffered whole in memory
- tests/_bootstrap.py: add every Lib/python3* directory; Package Control
puts the libraries under the active plugin host's own directory
