The above took me a few reads to understand what it wants to say,
probably because the "and when trace2 is enabled" comes a bit too
late to explain why "try to open other" is done. After reading it a
few times, here is what I think it wants to say:
After opening a bitmap successfully, we try opening others only
because we want to report that other bitmap files are ignored in
the trace2 log. When trace2 is not enabled, we do not have to
do any of that.
