BZ #191: Intermittent shutdown failures

Status fields:

The buildbot test runs – interestingly (almost) only on i386 – occasionally fail like
this:

Exhibit 1: http://c1.complang.tuwien.ac.at:8010/builders/cacao-classpath-i386-clang-
fast/builds/444

The problem is that the threadlist lock is being removed by a global destructor while
still in use.

Seems to be eliminated for classpath builds, but running the bugzilla regression tests
with OpenJDK still results in:

I don't know of any outstanding issues with this one.
