Thanks.  That would mean a single change is the culprit, but I need
a way to reproduce the problem to be able to fix it (other than just
reverting the patch).

That's a bit heavy as far as testcases go.  Thing is, I can't reproduce
it.  If that's a generic problem, shouldn't this also occur when trying
to start a program from bash or tcsh?  I deliberately removed a DLL from
my system, but there is no hang at all when trying to start an affected

Can you please provide a simple testcase?  If you can reproduce it with
given binaries from the distro, I don't need source code, just the steps
and the names of the binaries to reproduce.
