Comment (by ned14):

 I had a look for the testcase I wrote for #9856 but it looks like I
 deleted it last time I reset my Boost installation.

 However, if I am to be blunt here, this must be a behaviour which differs
 between people's machines. Perhaps an AMD vs Intel difference, or maybe a
 HPET difference? On Windows it also matters hugely if any multimedia
 program is running because then the Windows context switch granularity
 goes from ~43ms to ~1ms. A multimedia program famous for this is the
 Chrome web browser.

 Obviously whether a multimedia program is running should make no
 difference to Boost code. But I am trying to think of a repeatable
 demonstration, as otherwise finding and fixing any problem is very hard.
