viq
This class contains utilities for accessing and manipulating the labels of the current thread;
it also provides launch, shutdown, registerService, getService, fork, call, getRoot and setRoot.
Assuming that the current thread acts for principal p1, and p2 isn't the public pid,
and p1 is a node in the delegation graph of this, the delegate method gives authority
for this to grantee p2.
