Also: was this tested with projects or sessions large enough that the file IO starts being affected by the number of files in the directory, on file systems (and/or -fragmented- HDDs) where this can become an issue?

I'm not unwilling here, but utterly unprepared. I've done a bit of tinkering though, and from the looks of it the files are written only after all queued files finished being parsed, so that part at least will unlikely be a bottleneck.

It also seems that the code is designed to cope with write failure. Exactly would you miss/lose when these topcontext files are not saved?
