Bob Lantz e1246c3741 Simplify port specification. 
For the moment, I've removed the ability to specify
a dict of options without using **. This is a slightly
unfortunate trade-off since it simplifies implementation
at the expense of making the API slightly less convenient
(if somewhat more consistent.)
 2012-03-25 15:39:18 -07:00

Bob Lantz 28833d864c Retry deleting cgroup for the moment because it seems flaky. 
Ultimately we may wish to create a mininet/ cgroup and do a recursive
delete at the end.
