Sorry, sorry, sorry.  I've been wrong.  I had opened the test buffer.c
buffer already before I've set jit-lock-defer-time to zero, and then the
new value had no effect on that buffer.

Now I can confirm that j-l-d-t = 0 fixes both the display freezes and
the non-fontified bug report or byte-compile buffers.

Bye,
Tassilo
