Most useful would be the "show alllocks" from DDB.  Getting the lock
information from kgdb is rather more annoying, though jhb has some gdb
scripts which help. (http://people.freebsd.org/~jhb/gdb/)  I guess the
'allchains' command from gdb6 is the one in question, but it's been a
while since I tried to use these scripts.
