I seem to recall that PATH_MAX is not really PATH_MAX :) It can be +10
ish... for the " (deleted)" that gets appended if things are
unlinked... just something I sorta recall rolling around the back of my
head and I haven't really any idea if it is applicable here in any
way...

I don't think so. The concern is PAGE_SIZE is to big for a message, so lets pick something else

to truncate the message size on, the suggesting was PATH_MAX which makes sense

and works in this case.

The patch I have on top of what I submitted so far is to pick PAGE_SIZE or PATH_MAX, whichever is

smaller.
