[Lazarus] What are the perfomance and memory usage effects of having heaptrc running?

[vfclists .]

I want to use heaptrc in a program, but only use the
AddExitProc(@DumpHeapTraceOutput) occasionally with a command line switch.

Does heaptrc intercept and monitor memory allocation throughout the program
execution, or does it do a scan of memory usage for output only at program
shutdown?
