I was running a script and accidentally hit Control+T instead of Command+T to create a new tab. I was surprised at what I got. Here is an example of what gets printed:
# buildOrder.py load: 2.51 cmd: p4 15179 running 0.00u 0.00s load: 2.23 cmd: p4 17962 waiting 0.01u 0.00s load: 2.53 cmd: Python 15167 running 94.68u 66.33s load: 2.60 cmd: Python 15167 running 150.71u 101.82s
[crarko adds: I wasn't able to reproduce this, but it may be due to the briefness of the running command. Give it a try and post a comment about your results. Try it in Snow Leopard too if you can.]
