After my other patches I've posted recently to current@, sscdisk(4) is the 
last remaining driver that uses DISKFLAG_NEEDSGIANT.  I've added some simple 
locking to it that compiles (not runtested).  Not sure if anyone is capable of 
testing it since it requires HP's SKI emulator.  We should either commit this 
or remove SKI support though as I want to retire DISKFLAG_NEEDSGIANT in 10.
