Subject: [PATCH] Since tempfiles seem to occasionally be left behind, allow
 logging of open tempfiles, including a traceback (to determine callers) if
 LOG_TEMPFILES is set in the environment when Galaxy starts.  This should be
 considered temporary and will be removed when it's determined where/how this
 happens.
