This was why I used globs in the first place.
To answer Jakub's question first: yes, some of those are holding locks
open while things are happening. Since there's locks open, through a
lot of functions, it's
Generally speaking I'm pretty good about opening and closing the files
when it's needed. I *THINK* they can be made local variables, as I
don't think anything is kept open (within the caching engine) across
functions.
I've made a couple of changes, I'm going to have to test them, this
might be fixed in v9.
