## Detailed Description

Token waiter list.

Not a public interface. This queue holds all the token proxies waiting for ownership of a token. Along with the proxy reference, it also stores the nesting level, client id, and a magic cookie from the proxy. This queue stores the ACE_TPQ_Entries by pointer values. It DOES NOT make copies. Thus, the user is responsible to ensure that the TPQ's stick around. This is motivated by the need to reduce dynamic memory allocation.
