I had forgotten that even for a static project, I still call
NSFileManager's fileExistsAtPath: on re-activation, to detect if any
files has gone AWOL since last use (I'll be sure to also do that lazy/
async. in 1.2).
I can easily swap the code with something more low-level as a quick
fix, but I'm too pressed for time to experiment with this myself
(benchmarking the alternatives etc.).
