  Log:
  Partially revert previous commit. Calling getit() unconditionally fixed
  a problem that could also be fixed differently without reverting previous
  attempts to fix DELAY while the debugger is active (rev 1.204). The bug
  was that the i8254 implements a countdown timer, while for (k)db_active
  a countup timer was implemented. This resulted in premature termination
  and consequently the breakage of DELAY. The fix (relative to rev 1.211)
  is to implement a countdown timer for the kdb_active case. As such the
  ability to step clock initialization is preserved and DELAY does what is
  expected of it.
