Summary: COMI: crash during death sequence

Initial Comment:
There is a reproduceable crash here during the sequence
after taking the spiked drink.  This doesn't affect
Kirben on windows and has been reproduced by endy.

Boot param 620 is the easiest way to test it.

Currently its believed that the following change
http://cvs.sourceforge.net/viewcvs.py/scummvm/scummvm/scumm/imuse_digi/dimuse.cpp?r1=1.34&r2=1.35
may have been what introduced the problem.  It was not
present with a CVS checkout from the 15th January.

Running via gdb and giving a SIGINT (^C) after the
crash resulted in the following backtrace:

#0  0x401e2236 in __lll_mutex_lock_wait () from
/lib/tls/libpthread.so.0

I'm running latest CVS, latest and greatesst from
Debian sid on x86 Linux. This doesn't affect Kirben on
windows and has been reproduced by Endy who is also
running Linux.
