I talked with Jim about it off-list. He indicated that the factors are:
Username, hardware, OS, machine name, nickname and gcc version.

I had upgraded my Linux kernel from 2.6.17 to 2.6.18. I suggested to Jim
that changes in the minor revision number of the operating system should
not count as a new machine. He said he'd look into it when he has time.
Its not a huge issue, I just didn't want to be incrementing the machine
numbers needlessly and needed to know what it was based on.
