Added special logic to faciliate profiling the test suite run with the cProfile.py 

module.

On my MBP running SnowLeopard:

$ DOTEST_PROFILE=YES DOTEST_SCRIPT_DIR=/Volumes/data/lldb/svn/trunk/test /System/Library/Frameworks/Python.framework/Versions/Current/lib/python2.6/cProfile.py -o my.profile ./dotest.py -v -w 2> ~/Developer/Log/lldbtest.log

After that, I used the pstats.py module to browse the statistics recorded in the my.profile file.

o Profiling dotest.py runs
I used the following command line thingy to do the profiling on a SnowLeopard
machine:
$ DOTEST_PROFILE=YES DOTEST_SCRIPT_DIR=/Volumes/data/lldb/svn/trunk/test /System/Library/Frameworks/Python.framework/Versions/Current/lib/python2.6/cProfile.py -o my.profile ./dotest.py -v -w 2> ~/Developer/Log/lldbtest.log
