Abstract:
CClientOxid objects represent OXIDs which are in use by one or more clients
on this machine. These are referenced by
is pinging the server of the OXID. These objects maybe kept around
after the last client reference to improve performance.

Class Description:
Represtents an OXID on some machine.
Members:
_plist - Embedded CPList element used to store CClientOxids
in gpOxidPList.
_oxidInfo - Static information about this OXID and its
string + security bindings.
_pMid - Pointer to the machine ID for this OXID, we
own a reference.
_fLocal - non-Zero if this OXID is on this machine. Need only 1 bit.
_fApartment - non-Zero if this process is prefers apartment model.
Meaning less for non-local OXIDs. Need only 1 bit.
