That's very plausible.  The chdir was removed because its not safe to do
chdir in multi-threaded programs, and QMTest can provide parallelism via
threading.  If your test class is invoking an external program, you can
have that external program do the chdir, if you like.

Thank you for the bug report.  We're working on fixing that link.  Here
is the current internals manual, which is a little more current than
2.3, but should still be useful to you:
