#12744: winapi::set_timer_resolution inadvertently changes timer resolution
(Windows)
------------------------------------+--------------------------
 Reporter:  Terry Kim <yuminkim@…>  |      Owner:  igaztanaga
     Type:  Bugs                    |     Status:  new
Milestone:  To Be Determined        |  Component:  interprocess
  Version:  Boost 1.63.0            |   Severity:  Problem
 Keywords:  timer resolution        |
------------------------------------+--------------------------
 boost::interprocess::ipcdetail::spin_wait calls
 get_system_tick_in_highres_counts(), which ultimately calls
 winapi::set_timer_resolution() to get the current timer resolution.
 However, this changes the timer resolution inadvertently.

 I verified this with PwrTest.exe
 (https://msdn.microsoft.com/windows/hardware/drivers/devtest/pwrtest).

 Can we use winapi::query_timer_resolution() instead of
 winapi::set_timer_resolution()?
