By "tiny fraction of users" I was referring to people who a) work with
Python 3.3+, b) use time.monotonic in their code, and c) possibly have said
code running on versions of Windows older than Vista; not people who
suspend their systems or use VMs.

It's not clear to me whether those cases are relevant to the rollover
concern anyway. I wouldn't be shocked if the GetTickCount() function simply
stopped increasing while the system is suspended, since after all it's not
"ticking" during that time.
