Is this also true for passive translators?  Do they also not store the
path to the translator executable (as I've thought until now) but a direct
reference to the file instead?  If so, what would happen if the translator
is replaced by a newer version for example?

Or is the path for passive translators stored in the inode but looking up
the executable does not cause the same translator to be queried again?

I've realised that several times already :)

Anyway, I'm just curious.  If answering my questions above would take to
much effort I'm as happy to be told that there is no problem and I needn't
worry...

Or maybe the information I need is available somewhere in the docs?
