In "do_stop" there is a call to "do_close" which does "cryptsetup remove"
or "cryptsetup luksClose" (if the use count of the device is 0).

Also, in an earlier msg to the same BR, you seemed to indicated that
strider-home_crypt and strider-swap_crypt were removed when
/etc/rc0.d/S48cryptdisks was executed...that would indicate that
"cryptsetup remove" was indeed executed.

I'll take a look at this later today if I have time. Meanwhile, could you
add some debugging output to "do_close" in the cryptdisks.functions script
and retry a shutdown?
