--- Comment #4 from Glen MacDonald <glenmac at uw.edu> ---
Hi Wayne,
thanks for the cleanup on the macro. I still have much to learn (or remember).
I ran it on 5 Macs, all OS10.9.5, latest Fiji 1.49m RC24, Java 1.60_65. oldest
was Early 2009 MacPro, newest was Late 2013 iMac. All gave variable results:
sometimes releasing all memory at each interation, sometimes retaining 1,2 or 3
stacks or a montage until the next montage loop, other times releasing nothing
on every montage.  I'm not seeing that the garbage collector is doing anything
when clicking on status bar or calling from the macro. Behavior is different
every time Fiji starts up.  I've read that too many GC calls can result in OOM
errors. Could there be Java settings I should investigate?  I've never before
had an iterative operation behave like this.  Interestingly, the older 2 macs
had more OOM, they are Xeons instead of i5 or i7.  

Regards,
glen
