a few typos

[Glen Kaukola]

Sorry in advance if this isn't the appropriate place for this sort of 
thing, but I've noticed a few typos in the documentation:

Line 1110 of ipc.tex should probably read "the server remains safe from 
potential DoS attacks" and not "the server remains save from potential 
DoS attacks"

And line 433 of vmm.tex should probably be "To facilitate this..." and 
not "To facility this..."
