That's more or less. I wanted to call display-warning, found that it
was too soon, and looked for a way to delay it.

Yes, like the malloc low-memory warning code does. Fine by me. The
problem I wanted to tackle was warning about default HOME, not
designing a delayed warning facility :-)

Only I would process `display-delayed-warnings' in reverse, so C code
can add with

  Vdisplay_delayed_warnings = Fcons (..., Vdisplay_delayed_warnings);

but the user still gets the warnings in order.
