Memory leak in kpathsea?

[Jonathan Fine]

Hello

The attached shell transcript shows that when TeX repeatedly
inputs /dev/null, then memory use (the last numeric output in
the output of ps) grows without bound.

Perhaps an expert could confirm (or deny) my diagnosis, that
there is a memory leak in kpathsea.

BTW, I'm not a subscriber to this list, so I'd very much
appreciate being cc'ed on the discussion.
