Thanks, Eliot. Loaded and working. 99.7% of my code I was profiling was creating a big prime number for use in branding. My startup is 4 secs per CapTPManager and I use 2 to 3 of them in each test case. I was wanting to speed up my test cases.
Thanks!

Eliot,
I noticed that MessageTally was broken in Cog (which may or may not have anything to do with Coc). It broke in MessageTally>>#spyEvery:on: inside the following code:
"Collect gc statistics" SmalltalkImage current getVMParameters keysAndValuesDo: [ :idx :gcVal | gcStats at: idx put: (gcVal - (gcStats at: idx))].
gcVal was nil for index 4. I looked at all the VMParameters and there are several nil values. Is this a Cog thing?
Yes. There are several vm parameters which are obsolete in Cog. Answering nil is IMO better than answering some fake value such as 0. Better to provoke an error when fed with bad data than to hide the bug.
Should all VMParameters be non-nil?
IMO, no.
Should MessageTally change to protect against nil values?
