/dev/rst0 'Device busy' problem

Subject: /dev/rst0 'Device busy' problem
From: Joe Szedula <szedula@mindspring.com>

I was using 'star' {star 1.4.1 (i386-unknown-openbsd3.2)} to restore 
files from a tape backup using:

  star -n -f /dev/rst0 list=list_of_files

I got an error (appended to this message along with 'dmesg' output) and 
now accesses to "/dev/rst0" always return 'Device busy'. 

# mt -f /dev/rst0 status
mt: /dev/rst0: Device busy
May  1 11:57:52 mysys /bsd: st0: already open
May  1 11:57:52 mysys /bsd: st0: already open

Short of restarting my system is there a way to clear "/dev/rst0" so it 
is no longer busy? I've tried killing (using 'kill -9') the 'star' 
process but that didn't work. The 'ps' information is:

# ps -aux
USER       PID %CPU %MEM   VSZ   RSS TT   STAT STARTED       TIME COMMAND
root      6671  0.0  0.0   168  8516 p0  DE    10:36AM    0:12.49 (star)

Anyone have any ideas?

Thanks,

Joe
