Warning the underscore at the start of the name of this instance variable indicates that, even though it is not technically private, it is intended for internal use within the package, and you should not use the variable in other code.

assignGloballyUniqueBytes:
buffer
Fills the supplied buffer with 12 bytes that are unique to the subnet. The first two bytes encode a sequence of the process. Then two bytes encode the process ID followed by four bytes which encode a time stamp. The last four bytes encode the IP address. The caller must insure that the buffer pointed to is large enough to hold the twelve bytes.

EOGlobalID variables

This notification is intended to allow EOTemporaryGlobalIDs to be replaced with the corresponding EOKeyGlobalIDs. In theory one could interpret this as a mechanism to allow primary key attributes to be mutable class properties. Even though EOF also posts this notification in that case, it fails to consistently propagate the new value through relationships. GDL2 may attempt to correct that shortcoming in the future, but it may have serious performance implications.
