Comment 15 for bug 713879

Okay, I added a couple of ulimit checks to the byobu -v path. It costs a fork (0.01s) for each of the shell outs to ulimit, which shouldn't be necessary in the default code path. However, I can see this being useful if someone runs 'byobu -v'. Thanks for the information. Ping me if you guys find any other ulimit values/limits worth testing! Cheers!
