possible bug in amcheck?

Greetings all;

I had a hard lock last night while amanda was running, cpu overheat I 
think.  Had a bit of what for getting it going again, and the amanda 
recovery has been, lets say "interesting".

Not while doing a recover per sei, but in getting amanda back amoung 
the living in terms of caught up with her flushes etc so I can run 
normally tonight.

Due to my foulup in modifying one of my scripts, it was falling thru 
to the amcheck at the end of the script while the drives buffer were 
still being flushed.

Amcheck spits out an input/output error since the drive is already 
busy, BUT, it apparently goes right on ahead and increments the 
tapeslot file, such that for instance, while the magazine is set for 
the 3rd tape, amcheck *thinks* its the 4th & last tape.  Not finding 
a match, rather than going to the next slot, it reverts to slot 0 and 
starts the scan all over, but never getting to the true 3rd slot, 
called slot 4 on the front panel of this drive.
Here is the result of one such run:
---

The changer was actually sitting with slot 2 loaded when I started 
that run.  All this is a bit confusing too when amanda uses a base 0 
slot number, but the drive uses a base 1 numbering system.
But now that it knows for sure what slot is which again, so the next 
run will be successfull, as follows:
---
amanda@coyote amanda]$ amcheck DailySet1

match)

is there not a handy workaround for this, other than putting another 
10 cycles of wear and tear on the tape headers?
