- rotate boot.log per boot cycle (might be easiest to just fork/exec out to logrotate directly)
- fix error handling. In particular, ply_open_module gets it completely wrong (replies on errno instead of dlerror())
- consider moving text code from ply-window to a ply-text-buffer analog of ply-frame-buffer
- restore text color palette on exit
- maybe watch for VT switches and do things like restoring text color palette and stopping drawing the framebuffer
