Scalability Testing

[Keith Hodges]

So.... as I am scalability testing, I see that my magmaSession 
cachedObjectCount is now 90000, i.e the whole database is in memory, and 
still growing. Isn't smalltalk great I can rewrite the code while the 
test is running.

So I figure if I can hunt down who is holding references to the 
datamodel and get them to let go, the cached object count and my memory 
usage will fall.

I track down one instance of something permanently referencing the root 
and re-code that.
I also notice that due to the design of my Scalability testing framework 
it is holding at least one reference to the model in an instance var, 
even when it is paused and not doing anything. So I recoded it while it 
is running. Still 90000 object count. Where can it be?

How does one track down the offending item?

Keith
