It is desired behavor with undesired side-effects. I knew I should have put this through the beta phase first (it always hits me if I try to shortcut changes...).
Please see this (external) bug tracker:
https://bugzilla.redhat.com/show_bug.cgi?id=136141I will now see that I change it so that stderr is closed after the initial initialization. Sorry for the hassle, this case once more reminds me that *all* changes except *real* bug fixes belong into the master branch only. I'll see if there is an easy fix, else I remove that functionality from 4.2.0 and introduce it to 4.5.0 again.
