Is there any way to run a system on a true fixed timestep (for polling etc)?

[bcolloran]

The migration notes for 0.10 mention that the fixed timestep functionality in Bevy "is not intended to serve as a looping timer to regularly perform work or poll".

Is there any way to set up this kind of looping timer to run some systems on a fixed cadence (independent of the user's monitor refresh rate, which near as I can tell seems to act as the master timer for everything in Bevy), or is it just not possible at all currently?
