Nope... let's go through this and see what the server would do...

Is caller_perms() a wizard?  Yes?  OK, set prop #110.wizard to 1.
Is caller_perms() a wizard?  Yes?  OK, change task perms to #110.
A fork... ok, I'll do that code in 1 second...
Is caller_perms() a wizard?  Yes?  OK, set peop #110.wizard to 0.
(a second later)
a shutdown():  caller_perms().wizard?  No.  E_PERM.
