Please describe the problem:
I've tried this with python 2.5 and 2.6 as well.  When I import ldtp from
python, the interpreter just hangs, and will not accept further input.


Steps to reproduce:
1. 'import ldtp' from python



Actual results:
interpreter hangs

Expected results:
doesn't hang

Does this happen every time?
yes

Other information:
I did an strace on the python process and saw this:
Process 2752 attached - interrupt to quit
futex(0x891106c, FUTEX_WAIT_PRIVATE, 1, NULL^C <unfinished ...>

I also bisected and found that it started failing with this patch:


I've verified that this bug exists in upstream as well, and bisected to find
the offending changeset:

        * ldtputils.py (GtkImportThread): Added new class which helped
        LDTP to work as earlier in performance. But this one broke the
        wnck get window list. Need to investigate.
