I imagine the index is opened for write access just in case anything
is written to it - if nothing is written to it, my guess is that its
date-time stamp reflects when it was opened, else its date-time stamp
would show when it was modified.

I think Jean-Pierre Radley (or it could have been John Esak) pointed
out this index file behavior to me about 35 or 40 years ago,
