Ok, here it is:

     ----->  APP STARTUP PRINTS:
     start sb_reset_dsp
     done RESET 1
     done tenmicrosec
     done RESET 0
     isa_dmastart: channel 5 busy

     ----->  THEN WHEN I CTRL-C, I ALWAYS SEE THIS:
     dmabuf 2 
     dmabuf 1 

     ----->  IF THE /dev/dsp close() DIDN'T HANG, THAT'S IT.

     ----->  BUT IF THE close() HUNG, I SEE THIS LINE AGAIN AND AGAIN, PRINTING
     ----->  ONCE EVERY 10 SECONDS:
     dmabuf 1
