The strace as in other comments gave (and it wouldn't
ctl-c, I had to kill -9 the strace):
Process 3843 attached with 9 threads - interrupt to quit

Is file descriptor 16 that second last line? The TCP connection to
the CUPS server? Also, what is the FD=DEL line near the top
of the lsof output on /SYSV00000000? I'm not expert enough to make total sense
out of all of this. Need any more output?
