Anything, I do mean anything, can be simulated using small test
programs. Pointing at a big fancy machine with lots of storage
and disk is a passive aggressive way to avoid the real issues,
in that nobody is putting forth the effort to try and come up
with an at least publishable test case that Christoph can use to
help you guys.

If coming up with a reproducable and publishable test case is
the difference between this getting fixed and it not getting
fixed, are you going to invest the time to do that?
