 It's so odd that I switched kernels twice just to make sure it was no
 fluke.
 
 
 BTW: ps(1) told me that every /dev/lpt0 writer hangs in lptwrit, which
 I assume is the truncated version of `lptwrite2' somewhere in lpt.c.
 
 Also interesting: The LED on the printer that indicates incoming jobs,
 turns on as soon as a writer enters lptwrite()/lptwrite2.
