After some private discussions and testing, I've given up trying to fix
this issue and reverted most of the changes made by
4f2228fb1d7527fb5ebc8b2d747c309f1dd7698d (excluding some in unit tests)
with f1cbe93b6c0a8607a7e3cfb732c0eece7c64a029.  I've also marked the new
tests in epicsEventTest as TODOs.  This will have to wait for someone
with time and access to a test system to sort out.

Title:
  callbackRequestDelay not waiting for 1/60 sec on vxWorks

Status in EPICS Base:
  Triaged

Bug description:
  The problem is documented in this tech-talk thread:
  https://epics.anl.gov/tech-talk/2020/msg00308.php

  In 7.0.3.1, but not in 7.0.3, callbackRequestDelay(1/60) results in
  100% CPU time, most of the time in cbHigh.

  This happens on vxWorks 6.9.4.1 and was first seen with the scaler
  record with multiple types of scaler hardware and device support.
