I'm far from a bash expert, but my understanding is that exports in scripts only affect child processes of that script, but not the parent environment. This was a surprise to me.

If I run rmem on the command line and then run env, I don't see these settings. But I can get them to 'stick' by running . rmem.

My testing has confirmed this, but I could easily have missed something about how bash works.

Huh, cool. I didn't know that. Thanks for the blog post! I'm still playing around with settings a bit, but I'm down from 25 minutes to about 410 seconds :D
