[yum-cvs] yum/rpmUtils transaction.py,1.23,1.24

[Menno Smits]

Update of /home/groups/yum/cvs/yum/rpmUtils
In directory login1.linux.duke.edu:/tmp/cvs-serv2539/rpmUtils

Modified Files:
	transaction.py 
Log Message:
Fixes so that CTRL-C finally works properly:
    - rpmdb transactions are only kept open when strictly necessary so that
      SIGINT handler is left alone by rpm during downloads etc
    - added a simple interrupt_callback for package downloads. A single CTRL-C
      will push the download to the next mirror. Two quick CTRL-C's will
      terminate Yum. This needs cleaning up to not upset Yum API clients.
