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. Blushed: bde :-) Submitted by: bde
