Ah, I see what's happening (was quadra system bloat)

[Yates, Glen]

Huh?, Where an application is installed has no bearing on whether the app
uses memory in its own space or in the system heap. It's all controlled by
how the app allocates memory. If indeed Rev allocates memory from the system
heap, then to optimize memory usage on a low memory mac, you should decrease
the applications memory partition from the "Get Info" window. That will
leave more memory available for the system heap to grow into.
