It looks like there can be "commit comments?" *shrug*  In the future, should 
a Pull Request usually be created?  I didn't know if that sends some sort of 
"Hey, add this!" notification, or simply makes it show up as a PR.

I don't know what you mean by "disabled."  You mean the adjustment changing? 
I sort of already alluded to not thinking it's necessary to check it each 
time gettimeofday() is called -- I was already thinking of a much more 
complicated method last year involving that stuff, before finding this 
spring that Vista/7 aren't very finely adjustable like XP regarding 
*setting* SystemTimeAdjustment...

I know it could fail (though not sure why), technically, but I don't know a 
reason for checking.  time_update_rate is already initialized in time.c.

Why?  Just because?  I thought it's fine to use true globals when it's safe 
to (I've seen it in another place), like function pointers.  No threading 
issues when they're only modified during startup (1 thread).

I was glad to see Stas' reply to "let's see for 5.4" to, well, see if 
there's any other problems found. :-)  There's that uniqid() bug/issue like 
I said.

5.4 is also the last "official" release (with PGO) for Windows XP.

Thanks again for feedback,
